Find out the correct statement(s).
Show Hint
- Authigenic minerals form during diagenesis of sandstone.
- Heavy minerals in sandstone are good indicators of provenance.
- An arkose is mineralogically more mature than a quartz arenite.
- Matrix in sandstone may form by post-depositional infiltration and/or authigenic filling.
The Correct Option is A, B, D
Solution and Explanation
Step 1: Analyzing the statements.
- (A) Authigenic minerals do indeed form during the diagenesis process.
- (B) Heavy minerals are excellent indicators of provenance in sandstone, as their presence and composition can help identify the source rock.
- (C) An arkose is a more immature rock than quartz arenite, as it contains a higher percentage of feldspar.
- (D) Matrix in sandstone can form by post-depositional processes.
Step 2: Conclusion.
The correct answer is
(A) Authigenic minerals form during diagenesis of sandstone.
(B) Heavy minerals in sandstone are good indicators of provenance.
(D) Matrix in sandstone may form by post-depositional infiltration and/or authigenic filling.

- Which one of the following primary sedimentary structures is NOT used for palaeocurrent analysis?
In a sedimentary succession shown in the figure, the last occurrence of the fossil species Q (dated 50 Ma) and the first occurrence of the fossil species R (dated 30 Ma) are recorded at Y and X, respectively. The estimated rate of sedimentation is (assume constant rate of sedimentation).
- In clastic sediments, the correct order of decreasing grain size is
Match the primary sedimentary structure in Group I with the corresponding process of formation in Group II.
\[\begin{array}{|l|l|} \hline \textbf{Group I} & \textbf{Group II} \\ \hline \text{P. Asymmetric ripples} & \text{1. Water escape} \\ \hline \text{Q. Dish and pillar} & \text{2. Bed load transportation of sediments} \\ \hline \text{R. Flute cast} & \text{3. Deposition from alternate traction and suspension load} \\ \hline \text{S. Wavy bedding} & \text{4. Scouring by turbulent eddy} \\ \hline \end{array}\]From the data shown in the table, the weighted mean size (in micrometer, correct to two decimal places) of the sediment population is ............
\[ \begin{array}{|c|c|} \hline \text{Grain Size (micrometer)} & \text{Dry Sediment Weight (in gram)} \\ \hline 4 & 50 \\ 20 & 75 \\ 40 & 125 \\ 60 & 50 \\ \hline \end{array} \]
