Shulamit Gross (Hebrew: שולמית גרוס; lived 1 October 1923 – 19 Sep 2012) was an Israeli mineralogist and geologist who studied the Hatrurim Formation.

[1] She began a PhD in the Radioactive Micas of Central Asia, but was not permitted KGB security clearance, and her studies were terminated.

[1] During the 1960s, a group of scientists from the Hebrew University of Jerusalem, including Yaakov Ben-Tor, and Lisa Heller-Kallai, discovered that the Hatrurim Formation contained several rare, if not unique, mineral assemblages.

[1][2] These rare minerals only form at high temperature, for example in places where siliceous limestones are contact-metamorphosed by volcanic rocks (commonly basalt).

The manufacturing of Portland cement involves a similar process: heating of limestone or chalk with siliceous clay at high temperature (1450 °C).

[2][4][5][6] A fourth mineral discovered by Gross was only described later by Dietmar Weber and Adolf Bischoff, which they named grossite after Shulamit.
