Talcum powder (also known as baby powder) is made of talc, a mineral consisting of magnesium, silicon, and oxygen. Talc is obtained through mining mineral deposits, which are often intermingled with deposits of a type of asbestos known as asbestiform is most dangerous when it is friable, meaning that it is powdery or crumbles easily, producing tiny inhalable fibers.
The Mohs scale of mineral hardness is based on scratch hardness comparison, ranging from 110, a value of 10 being the hardest of minerals. Talc is the defining value 1 therefore the softest of minerals. Any mineral below a value of 2 on Mohs scale of mineral hardness can be scratched by a fingernail.

The talc deposits are consistently associated with a carbonate horizon of the Crystal Spring Formation where it was intruded by regionally persistent gabbro sills. This sillcarbonate rock contact zone contains talctremolite rock, which has been mined from 1910 to present. Talc mining ended in 1988 in the mining claims that are now within DVNP.
Talc is an important accessory mineral and can be found worldwide. Crystallized Talc in very small crystals comes from the Trimouns Talc Mine, Luzenac, France; and from Brosso, Lessolo, Italy. Excellent Talc pseudomorphs, especially after Quartz, are famous from the Johannes Mine in Göpfersgrün, Bavaria, Germany.

Talc formation and deposition: The formation of talc occurs in separate geological environments. The talc deposits are different from each other on the basis of current composition and also on the parent rock composition from which it is derived. The talc deposits can be categorized into four types.
Talc ores also differ according to their mineralogical composition ( the type and proportion of associated minerals present). They can be divided into two main types of deposits: talcchlorite and talccarbonate. Talcchlorite ore bodies consist mainly of talc (sometimes ) and chlorite, which is hydrated magnesium and aluminium silicate.
Presence of Asbestos in Talc 4 largest production of commercial talc (Bateman, 1951). Within the United States, New York State is the leading producer because of its large deposits in St. Lawrence County (Loomis, 1948). North Carolina has several large deposits .
Talc is a hydrated magnesium silicate. There are many types of talc and each ore body has its own features, its own geology, formed many millions of years ago. As a natural ore, talc is always found in combination with at least one other mineral. The most common of these is chlorite, a chemically and structurally similar ore.

Talc Deposits. Commercial deposits of talc lie between Johnny Gulch and Cherry Creek in an area about 5 miles long by miles wide. The talc deposits occur as isolated bodies in relatively pure marble. The Johnny Gulch deposits were discovered by (or Louis) Clark on his homestead shortly after 1900 and were later opened by shallow pits.
