COURSE STRUCTURE
The EME course forms a key part of the Geology, and Geology & Physical
Geography (GPG) Honours degree programmes.
Details of the marks
applicable are given in the 4
th
year Honours booklets for Geology and
GPG.
The style of teaching and lecture content diff
ers somewhat from previous
years and you should be prepared for this. During 1
st
, 2
nd
and 3rd years the
lectures commonly convey information that you are expected to know for
the exam. In contrast, the 4th year teaching (in preparation for the 'real
world'
) is generally an introduction to a selected topic, and you are then
expected to put in extra time into your own reading and thinking about the
topics covered. The course will draw extensively on material covered by
everyone in previous years and will brea
k new ground, as indicated below.
EME teaching consists of thematic lectures coupled with a small number
of integrated case histories. These are intended as supporting material.
Questions will not be set in the degree exam uniquely on these topics but
they
will provide geological examples which you will be expected to
incorporate onto your answers on the questions set, as appropriate.
The subjects covered in the lectures and integrated case histories are
principally related to the evolution of the Earth fro
m Late Precambrian to
Recent time. The course is loosely divided into 4 related components:
Framework topics (Earth & Mars), lectured by Profs. Ian Main and Kathy
Whaler; Modern and Ancient processes: Profs. Hugh Sinclair and Dick
Kroon; Continent
-
ocean in
teraction: Prof. Alastair Robertson and Dr Jenny
Tait; Integrated case histories: Prof. Alastair Robertson and Dr Andy Bell.
Reference list. You will be issues with a consolidated list references,
generally 2 key references per topic (session). These are
designed to
complement and extend the lecture content. For each lecture you are
expected to spend about 7 hours of reading and supplementary study. Be
sure to obtain your copies of these key papers. You may be given
add
itional references on a lecture
-
by
-
le
cture basis but the consolidated
reference list should be your priority for independent study.

The classes are normally held in the Main Lecture Theatre 201 Grant
Institute, but may on occasion be in room 304B in the Grant Institute (as
advised). The lectures will usually be held on
Monday at 10
-
12pm and
Tuesday
at 9
-
11am
.
ASSESSMENT AND COMPOSITIO
N OF THE EME THEORY
PAPERS
The EME course is examined by
one 3
-
hour
-
long theory paper
sat in the
Examination diet after Semester 1 teaching end. You will be asked to
answer three questions, one from Part A and two from Part B, with ample
choice.
Part A
is generally testing knowledge and understanding of EME topics as
they were presented, with the additional expectation that relevant material
covered in earlier years that has been developed and applied in fourth year
will also be incorporated in your ans
wer.
Part B will be interdisciplinary and reach across the structure of EME, and
could include topical issues of current Earth Science. It will again expect
inclusion of earlier relevant material, but in contrast to Part A questions,
may ask you to app
ly your knowledge in ways that have not been directly
addressed during the course. You might be asked, for example, to propose
a programme of field and laboratory investigation to elucidate the nature
of a particular kind of terrain in an orogenic belt, o
r to review possible
mechanisms of regional
-
scale uplift. A question such as that last one may
never have been addressed in any single lecture and will require you to go
back to first principles
–
what are the physical mechanisms which could
cause uplift,
and then what geological processes that you may have
encountered at some time in your courses over the years, or in literature
that you have read, could meet the requirements? You could also be asked
to interpret some data or a diagram.
Part A questions
are weighted more towards accurate recall, whereas in
Part B we look more for evidence of a capability to reason from first
p

principles and to demonstrate that you understand the logic behind
particular procedures, for example, the construction of a Rb
-
Sr
isochron
diagram, rather than just a knowledge of the conclusions drawn from it.
FORMATIVE FEEDBACK
You will be set a choice of several essays (similar to those to be set in the
degree exam) at the first meeting of Week 6 (Monday 21st October) and
you have one week later to answer one of the questions.
The essay is limited to 1000 words (not including d
iagrams and
references). Only hand
-
drawn, hand annotated diagrams should be
included of the type you would reproduce in an exam.
The essay will be assessed according to the following criteria:
• Clear organization with sub
-
headings;
• Correct facts and
clear explanation;
• Use of geological examples;
• Use of annotated diagrams;
• Citation of references (a few ones)
• Combining information from different lectures as appropriate;
• Analytical, critical and questioning approach
You should draw on the taugh
t material and your own reading in this
course, and also from other courses from Years 1, 2 and 3, as appropriate.
Better results may be gained if you prepare a draft of your essay within 5
days, and ask a fellow student to assess your work on the above cr
iteria.
You can then make any modifications. Submit a hard copy of your essay to
the drop
-
box in the Teaching Organisation in the Grant Institute while also
submitting an electronic copy via LEARN before 4 pm on Wednesday
30th October.

GRADE DESCRIPTORS
The Meaning of Grades in the Common Marking Scheme
What follows is a modified version
of the College Grade
-
related Marking
Criteria, here related specifically to the requirements of the EME course,
and intended to be a reasonable description of the criteria actually used by
the EME course teams.
Characteristic features of answers
in the m
iddle
of each class division are
outlined below, for each class division.
First Class
(Corresponding to Class A2 in the new extended Common Marking
Scheme, as detailed in the Grade
-
Related Marking Criteria (GRMC) from
College; see the extract in the Glg4
and GPG4 Assessment Regulations
Booklet.)
The candidate is completely at home discussing the material, having
a considerable depth of knowledge (main criterion in Part
-
A) and an
ability to produce a properly supported argument in a logical, ordered
seque
nce with clear understanding of the underlying principles
involved (main criterion in Part
-
B). There is clear attention to the
question as set, throughout. Signs (i.e. not extensive tracts) of
original thought in the form of arguments, observations or cr
itical
reviews of received wisdom that have not been presented during the
course. Evidence of reading from the recommended literature and
usually beyond, shown by reference to the sources of key ideas and
the location of important examples, but not necess
arily the full
bibliographic details. Clear diagrams are included, directly relevant
to the argument and fully incorporated into the answer, i.e. they are
p
13
p
13
an inherent and essential part of the answer, not just added for gloss
or padding.
Upper Second C
lass (mid 2.1)
The material is essentially correct, is well organised and generally
answers the question without major omissions but is largely drawn
from the lectures. Original arguments and lines of reasoning are
generally absent. Part
-
A answers are c
areful recall but the point of
the question frequently disappears from view under the weight of
worthy detail. Misunderstandings are generally absent but the actual
level of understanding is occasionally ambiguous as the writer
transcribes notes rather th
an presents a careful, well
-
constructed
argument. Part
-
B answers of the interdisciplinary type are
dominated by judicious splicing together of lecture material rather
than much newly constructed argument. There are some flashes of
original thought and de
finite attempts to answer the question and
cross boundaries, but this is not sustained throughout the answer.
First
-
principles
-
type answers are more or less sound but not
comprehensive in coverage. Data interpretation answers are solid,
covering the main
points but missing the subtleties, the alternative
interpretations and the penetrative analysis. Diagrams are sound but
not particularly well integrated or embedded effectively into the
progression of argument or explanation.
Lower Second Class (mid 2.2
)
The answer is incomplete with insufficient relevant information
presented and characteristic additions of irrelevant material by way
of attempted compensation. There are some good points but not
enough to merit an upper 2nd. There are some clear demonstra
tions
of understanding but some errors of fact and usually some clear
instances of misunderstanding. The dominant characteristic is a
patchwork of recalled material with poor links and no clear thread of
directed argument. Part
-
B answers are generally ch
aracterised by
Part
-
A
-
type chunks of recall rather than insight or incisiveness but
p
14
p
14
nevertheless manage to bring out some relevant points. First
-
principles
-
answers have one or two principles correct, others
incorrect and are usually bulked out with exampl
es without the
principles attached at all. Data interpretation answers get only some
of the main points correct and miss others altogether, along with
higher
-
order subtleties. Overall the answer has more reasonably
sound material in it than it has errors
and irrelevancies.
(There are however a number of ways to achieve a 2.2 which do not fit this
template exactly. All induce a feeling of considerable disappointment in
the examiner. Notably, there is the “tantalising fragment answer” that
contains a pa
ge or so of promising material but is simply too thin to merit
a decent mark. Then there is the “wilfully deviant answer”, that starts
well, gains some credit, but then becomes enamoured of its own voice and
sails off into completely foreign territory, of
ten quite accurately, but alas
with no relation to the question.)
Third Class
The answer has a bare minimum of correctly recalled facts and
relevant argument. There is much irrelevant material. Factual errors
and evidence of misconceptions are common.
Material comes
recognisably from the lectures alone, but is often much distorted.
There will be some evidence of understanding of the point of the
question or of the need to present a cogent argument, but not a great
deal. Answers are typically in the f
orm of a hopeful offering of
material, recalled with obvious difficulty. The answer nevertheless
passes the following two tests: does this candidate demonstrate a
level of knowledge and understanding greater than would be found in
a candidate who had not
attended the course but had the same
background? Does the candidate’s level of correct knowledge and
understanding manage to outweigh the evidence of
lack
of
understanding and
incorrectly
recalled factual material? Is this, in
fact, a “Senior Honours
-
lev
el answer”?
p
15
p
15
Fail
Answers do not pass the tests posed in the last section. Positive
features are either outweighed by misconceptions and errors or are so
vague as to be useless. Answers which completely fail to answer the
