Any four (x1) from: • Deposition/burial/compaction /lithification of Silurian sediment • Uplift/Folding of Silurian rock • Erosion of Silurian rock • Formation of a plane of unconformity • Devonian rocks deposited on top/after erosion/terrestrial or desert environment • Gradual processes operating over a long time period How many marks would you give this answer?
Mark scheme: 1 for concept related to the circulation of hydrothermal fluids 1 for dissolving trace elements 1 for concept of cooling and redeposition How many marks would you give this answer ?

Map 1 – Rock unit G is on top of Basalt (1) Rock G - is metamorphic therefore in the baked margin (1) Lava flow would not have an upper baked margin/sills have baked margins above and below (1)

What is the misinterpretation of the question here ?
This below scored all 3 marks for recognition that carbon capture is the essence of the question, that carbon dioxide is stored in depleted reservoirs, and that this will decrease the rate of global warming. Is there anything wrong with this answer that gained full marks?
The Applied Question in C2 There was an applied geology question related to map and other evidence gathered in component 2 The pale grey rock (D) at Locality 5 has previously been interpreted as Limestone What do you think the most obvious aspects are?
Any four x (1) from: Advantages • Limestone strong rock so stable dam foundations • Horizontal beds to the East - so stable • High run off from the east to fill reservoir Disadvantages • Leakage from faulting/jointing • Leakage from permeable limestone • Limestone collapse/sink holes • Fault movement possible so instability • Beds dipping away therefore leakage along the bedding plane

Is the answer of 38.2 worth any marks?
It was pleasing to see quite a number of correct answers though.
What is the error in this answer?
This is what we hoped to see, but the correct answer was seen less often than expected.
There were many answers like this. Not all the Maths questions are hard and this needs to be conveyed to candidates.
However there were still a variety of answers seen.
What do you think were the most common errors in answers to this?

Mineral Identification Some mineral identification questions simply require candidates to look up the one correct answer from the Data Sheet.
Mineral Identification Other mineral identification questions require more sophistication having looked up possible correct answers How many minerals have no cleavage and H = 5.5 or more ?
Mineral Identification The main issue candidates had was the need for more than one hardness test to conclude that H is between 2.5 and 3.5.
Candidates were able to identify that Mineral Q is calcite. However this is not the answer to the next question.
Fossil Identification
Recording observations To scale (1) Fault (1) One marker bed shown appropriately displaced either side of the fault (1) Accuracy of sketch (appropriate dip angles and bed thickness) (1) Additional bedding planes or joints (1)

2019-20 Assessment of Mapwork Skills
Drawing Cross-sections Guidance for teaching Geological Map interpretation and other aspects of the specification has been available as a recorded webinar available on the Eduqas website since Autumn 2018. This can be found towards the bottom of the GCSE Geology webpage
Drawing Cross-sections At AS candidates are expected to draw quite complex cross-sections onto an entirely blank profile. At GCSE candidates will only need to complete small sections of partially completed profiles.
Drawing Cross-sections In GCSE mapwork candidates will need to be able to deal with Igneous bodies; plutons, dykes, sills, lava flows Horizontal beds Dipping beds Folded beds and fold axes Faults: normal, reverse, thrust, strike slip Unconformities
A common error was to draw vertical beds instead of horizontal
Or to draw them continuing the ‘SE’ trend from the map
There were quite a few correct interpretations however.
