Which mineral identified at Neyveli in Tamil Nadu helped establish it as a Martian analogue site?
- A.Melanterite
- B.Gypsum
- C.Hematite
- D.Olivine
Correct answer
Explanation
The correct answer is melanterite. At Neyveli the mineral forms from marcasite in the lignite substratum through sulphide oxidation, and it records short-lived wet, acidic and oxidising conditions of the kind believed to have produced sulphates on Mars. Option B, gypsum, is also part of this study, but it was identified in the Atacama Desert of Chile and in the Tiruchirappalli Badlands rather than at Neyveli, so it does not answer this question; gypsum preserves evidence of older water-rich environments and can hold biosignatures in its mineral matrix. Options C and D name hematite and olivine, which are minerals often discussed in planetary geology but were not the ones reported in this work. Both minerals in the study are hydrous sulphates, meaning they lock water into their structure and therefore record how water and rock interacted in the past.

Practice Questions
Which institution's research team identified the Martian analogue sites using a laser Raman spectrometer?
- A.Physical Research Laboratory, Ahmedabad
- B.University of Kerala, Department of Geology
- C.Indian Institute of Astrophysics, Bengaluru
- D.National Centre for Earth Science Studies
Show answer
The laser Raman spectrometer used for the work is supported under the DST-FIST programme at that department, and the research team was led by Dr. Sajin Kumar K. S., who is the Project Coordinator of DST-FIST.

- A.Atacama Desert, Chile
- B.Sahara Desert, Africa
- C.Gobi Desert, Mongolia
- D.Kalahari Desert, Botswana
Show answer
Gypsum was identified there and also in the Tiruchirappalli Badlands, a semi-arid geological and palaeoclimatic terrain in Tamil Nadu, and both places therefore qualify as Martian analogue sites for the study of past water activity.
Read the full explanation →Which of the following is NOT one of the four pillars of the quantum programme supported by TDB?
- A.Identity security
- B.Location integrity
- C.Time integrity
- D.Climate resilience
Show answer
The four pillars are identity security, location integrity, network security and time integrity. Under identity security the project develops quantum-secure physical unclonable functions and quantum-safe trusted platform modules so that device identity is anchored in hardware.
