Talc is hydrated magnesium silicate (Mg 3 Si 4 O 10 (OH) 2); however, it may contain mineral impurities such as chlorites and fibrous amphiboles, calcite, magnesite, and dolomite. Talc has a characteristic perfect-basal exfoliation known as lamellarity or platiness due to low- to moderate-grade metamorphism during its formation.
serpentine. The talc ^eposit 1 *u worked by the Foliated Talc Company at Rove (pi. 2) lies between raica>chiat and amphibolita (Ladoo, 1923) and, aa there is no indication of serpentine at the miae^ the talc may have formed by alteration! ?., ., of the awphibolite or schist. Similar conditions exist at the deposit worked
Talc, a hydrous magnesium silicate that is commonly used for genital hygiene purposes, has been associated with ovarian carcinoma in multiple case-control studies [1,2,3,4,5].In addition, it has been known for decades that significant occupational exposure to talc is associated with lung disease [6, 7] and inflammation [8, 9].The assessment of …

talc may be contaminated with asbestos; therefore, talc products can cause mesothelioma. Indeed, "we found mesothelioma in cases exposed only to talc." Prudent and scientifically-astute judges, recognizing the leaps of logic, can reject the testimony on principles of admissibility of scientific evidence (Joiner v.
Four types of talc-induced lung injury are described in the literature. The first two are found in industry workers with recurrent occupational exposure to talc that leads to talc-silicosis and talc-asbestosis . Talc may also spread hematogenously to involve the lungs in intravenous drug users that self-inject talc-containing oral tablets [2,3 ...
It is believed that talc powder, when used near the genitals, can travel to the ovaries and become embedded in ovarian tissue.
