Cameroon GCE A-Level Geology study plan

Build a one-page reference sheet classifying silicate and non-silicate minerals by structure, cleavage and diagnostic physical properties, and self-test until you can identify 30 common minerals from written descriptions alone.

Explain in writing how the Cameroon Volcanic Line, the Adamawa uplift and the Congo craton margin control which rock types and minerals occur in Cameroon, citing at least five named localities.

Practise 20 mineral-identification reasoning questions where only hardness, lustre, cleavage, streak and specific gravity are given, and log every error with the property you misread.

Draw and label the internal structure of the Earth and relate each layer to the dominant mineral assemblages expected there.

Construct labelled sketches of the igneous, sedimentary and metamorphic rock cycles and annotate each arrow with the process and the Cameroon example that illustrates it.

Classify 25 rock descriptions into the correct petrological group using texture, mineralogy and field context, and justify each classification in two sentences.

Compare the petrogenesis of the Pan-African granitoids, the Tertiary anorogenic ring complexes (e.g. Ngaoundéré, Adamawa) and the volcanic rocks of Mount Cameroon in a comparative table.

Explain metamorphic facies series and apply them to the schists and gneisses of the Pan-African belt in northern and western Cameroon.

Interpret strike, dip and apparent dip from written numerical data and compute true thickness of a bed from three given borehole or outcrop depths.

Sketch and label the main fold, fault and unconformity types, then match each to a described Cameroonian or West African structural feature.

Explain the tectonic evolution of the Central African Fold Belt, the Foumban Shear Zone and the Benue Trough in a written narrative linking stress regime to structure.

Solve 15 structural problems on map-free data (three-point problems, fault slip, fold axis plunge) and record your method for each.

Build a geological timescale from memory (eras, periods, key boundaries in Ma) and attach one Cameroonian or African event to each period.

Identify the major invertebrate fossil groups from written morphological descriptions and state their stratigraphic range and palaeoenvironmental significance.

Explain the principles of stratigraphy (superposition, faunal succession, lateral continuity, cross-cutting relationships) and apply them to a described outcrop sequence to order the events.

Summarise the Cretaceous to Quaternary stratigraphy and palaeogeography of the Douala and Garoua basins, including the fossil evidence used for correlation.

Explain weathering, mass wasting, fluvial, coastal and volcanic landform processes and link each to a named Cameroonian landscape (e.g. the Mandara Mountains, the Sanaga drainage, the Limbe coast, the Mount Cameroon lava flows).

Interpret a written drainage-pattern description and deduce the underlying lithology and structure.

Calculate slope, stream gradient, sinuosity and discharge from supplied numbers and check units carefully.

Describe how lateritisation and tropical weathering profiles affect both landforms and mineral exploration in the humid tropics.

Classify ore deposits by genetic type (magmatic, hydrothermal, sedimentary, residual, placer) and give one African example of each.

Describe the geology, host rocks and economic minerals of Cameroon's key resources, including bauxite at Minim-Martap and Ngaoundal, iron ore at Mbalam, gold in the Batouri–Betare Oya area, rutile and the Douala basin hydrocarbons.

Explain the formation of lateritic bauxite and residual gold and relate the enrichment process to the weathering profile studied in Week 5.

Evaluate the exploration sequence from regional reconnaissance to resource definition and state which technique suits each deposit style.

Complete 10 geological map exercises from written descriptions: determine strike and dip, draw a cross-section, order the stratigraphy and identify the structure.

Compute scale conversions, real distances, vertical exaggeration and gradient from map data without a calculator error.

Write a full field-methods protocol covering compass clinometer use, logging, sampling, safety and data recording, as if briefing a field party.

Interpret a supplied borehole log and construct a simple lithological correlation between three described boreholes.

Sit two full timed mock papers under exam conditions and mark them strictly against the syllabus descriptors, recording the domain of every lost mark.

Re-teach your three weakest domains from your own error log by writing short explanatory notes and re-attempting the missed questions.

Recite from memory the mineral, rock, fossil, structure and deposit lists you built in Weeks 1–7, filling only the gaps you find.

Draft and memorise skeletal answer plans for the six most likely extended-response questions, each with a Cameroon-specific example.
