Maharashtra HSC Geology (MSBSHSE) case studies
Maharashtra HSC Geology (MSBSHSE) · Put your knowledge to work in context.
Geology at Maharashtra's Higher Secondary Certificate level is a laboratory-and-field science taught as an elective for Std XI and XII, examined by the Maharashtra State Board of Secondary and Higher Secondary Education (MSBSHSE). Students usually take it alongside Physics, Chemistry, Biology or Mathematics, and it suits candidates aiming at B.Sc. The Maharashtra HSC Geology (MSBSHSE) case studies are 5 cases and about 3,728 words.
1Koyna–Warna: fixing a drilling depth and an age for the same basalt flow
A final-year geology batch is working on data from the Koyna–Warna region of Satara district, where thousands of small earthquakes are recorded every year and where a 6 km scientific borehole has been proposed. Two data sets are on the table.

A 45 m thick basalt flow is exposed in a road cutting on the Ambenali section of the Mahabaleshwar–Poladpur ghat road. From bottom to top the field log reads: 0–1.5 m, glassy and vesicular fine-grained rock resting on a red bole; 1.5–12 m, dense fine-grained basalt with ophitic intergrowth of 0.3 mm plagioclase laths and augite; 12–25 m, medium-grained basalt with laths up to 2 mm, interstitial augite, and a few 3 cm pegmatoid pods of coarse plagioclase, augite and magnetite; 25–42 m, coarse gabbroic rock with 4–6 mm crystals and no vesicles; 42–45 m, strongly vesicular amygdaloidal basalt with zeolite and calcite fillings, weathered red at the top.

A mine-scale mapping project in the Wardha valley, Nagpur district, uses three boreholes 300 m apart on a north–south line. BH-1 (north) cuts the Barakar coal seam at 90 m; BH-2 (middle) at 210 m; BH-3 (south) at 95 m.

A four-storey hospital is proposed on a coastal plateau near Ratnagiri, about 700 m from a tidal creek. The site has 3–8 m of indurated, vesicular laterite over 12–18 m of weathered amygdaloidal Deccan basalt, with fresh basalt below 30 m.
