Question

Match the Volcanogenic Massive Sulfide (VMS)-type deposits in Group-I with the dominant mineralized host rocks in Group-II.

• A. P-2; Q-1; R-3; S-4
• B. P-2; Q-4; R-1; S-3
• C. P-4; Q-3; R-1; S-2
• D. P-1; Q-4; R-2; S-3

Hint:

The VMS deposits are closely linked with specific volcanic rock types: Besshi with mafic volcanics, Bathurst with felsic volcanics and siliciclastics, Kuroko with mafic volcanics, and Cyprus with felsic volcanics and siliciclastics.

Answer 1

The Correct Option is B

The Volcanogenic Massive Sulfide (VMS) deposits are typically associated with specific types of volcanic rocks. Let's go over the options:
Step 1: Besshi Formation (P)
The Besshi deposit is known to be associated with mafic volcanic rocks. Therefore, it matches with option 2, which is "Mafic volcanics + siliciclastics." Hence, P-2.
Step 2: Bathurst Formation (Q)
The Bathurst deposit is associated with felsic volcanic rocks that also include siliciclastics. Hence, Q-4 is the correct match.
Step 3: Kuroko Formation (R)
The Kuroko deposit is associated with mafic volcanic rocks, hence R-1 is the correct match.
Step 4: Cyprus Formation (S)
The Cyprus deposit is associated with felsic volcanic rocks along with siliciclastics. Hence, S-3 is the correct match.
Therefore, the correct answer is (B), which gives the correct matching: P-2; Q-4; R-1; S-3.
Final Answer:
\[ \boxed{(B)} \]
