Research
Gross was known for her research on the mineralogy of the Hatrurim Formation. In 1958, she began working at the Israel Atomic Energy Commission.[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. She moved to the Israeli Geological Society in 1961.[1] She became a PhD candidate at the Hebrew University of Jerusalem in 1964, working on "The Mineralogy of the Hatrurim Formation, Israel".[1]
Mineralogical analyses revealed that the rocks contain common minerals such as
She continued to study these rare minerals and in 1977 published a monograph describing 123 mineral species discovered in the Hatrurim Formation.[1][3] Five were previously known only from a single locality, and eight others were known only as artificial products of the cement industry. Gross also discovered several minerals completely new to science: bentorite, ye'elimite, and hatrurite.[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.[1][7][8]
She demonstrated that the unique mineral assemblages of the Hatrurim Formation were formed by pyrometamorphism, and she managed to recreate in the laboratory most of the minerals by heating the precursor sedimentary rocks of the Ghareb and Taqiye formations.
Her discoveries earned her the inaugural Rafael Freund Award of the Israeli Geological Society in 1979.[1][9] She became an honorary member of the Israel Geological Society in 1986.[1]
In 2011, a new perovskite-related mineral from the Hatrurim Basin was named shulamitite to honor Shulamit Gross for her works.[10][11] Shulamitite, ideally Ca3TiFe(III)AlO8, is a mineral intermediate between perovskite (CaTiO3) and brownmillerite (Ca2(Fe,Al)2O5), a mineral of the cement clinker. She died on September 18, 2012.[1]
