pitchblende

For example, 1979 hole BL-066 intersected 1,656 ppm uranium over 0.20 metres in a section containing visible grains of pitchblende, a uranium mineral commonly found associated with Athabasca Basin uranium deposits.

Primary minerals like uraninite, coffinite, pitchblende are found below water table while secondary minerals like uranophane, metatyuyamunite, carnotite are found in the the oxidized environments/above water table hosted by Vihowa group in Sulaiman, Manchar/Vihowa group in Kirthar and Potwar group in Kohat and Potwar basins.

While he was working in his experimental laboratory in Berlin in 1789, he was able to precipitate a yellow compound (likely sodium diuranate) by dissolving pitchblende Fig.

Devoting her attention to the mineral, pitchblende, uraninite ore, she reasoned that its emission of rays could be explained only by the presence in the ore of an unknown substance or substances.

Basically in Pakistan uranium is deposited in three types Uraninite, Pitchblende and Coffinite.
