The huge diamond treasure is

Research by a group of geologists at the National Institute of Geophysical Research in India suggests that it may have hidden a huge natural diamond mine that has been missed by previous polls.

Geologists from the National Institute of Geophysical Research in Hyderabad (southeast India) say the area has the basic ingredients to form a large diamond mine.

Diamonds form deep inside the Earth's crust and erupt onto the planet's surface thanks to volcanic rocks called kimberlites and lamproites . The team accidentally discovered volcanic rocks containing diamonds when they conducted another geological survey and decided to learn more about the area as a side project.

Geologist Subrata Das Sharma, author of the study, said: "The 200,000-square-kilometer area in southeastern India is likely to contain diamonds. We will use appropriate and effective exploration techniques. fruit to quickly search for diamonds on a large scale ".

Instead of finding rocks containing diamonds that are often easily crumbled and difficult to identify, geologists have devised many techniques for finding conditions for diamond formation in the coating (between the shell and core of the Earth). ). They then delineated to find the most potential areas.

Conditions for diamond formation are extremely high temperatures and pressures that are only found in the greatest depths of Earth's lithosphere (including Earth's crust and upper coating). Otherwise, carbon (the only component of diamond) will turn into graphite.

The thickness of the lithosphere fluctuates throughout the planet, not always reaching the depth needed to create diamonds.

Previous research was based on seismic data collected in a few earthquakes suggesting that southeastern India lies on the thin lithosphere. But Das Sharma's team reanalyzed the data with another technique and discovered lithosphere to reach the depth to form diamonds.

The team also examined the chemical composition of rocks on the nearby Earth's surface to confirm suitable temperature and pressure conditions for diamond formation.

Members of the research group plan to share their achievements with the Indian government and continue to improve research methods to develop more effective diamond hunting techniques.
