Formation timing and genesis of Madiu fluorite deposit in …
In this district, the large Madiu fluorite deposit contains five Mesozoic granite-hosted orebodies. The deposit may have formed at shallow depth and occurred as continuous veins controlled by a series of N-S- or NE-trending, steeply dipping faults. The fluorite mineralization can be divided into two stages (I and II).

Fluorite (Fluorspar) : Properties, Occurrence, Uses and Deposits
Fluorite occurs in hydrothermal deposits and as an accessory mineral in intermediate intrusive and silica-rich rocks. It is used in the manufacture of high-octane fuels and steel and in the production of hydrofluoric acid. ( Bonewitz, 2012) Name: From the Latin to flow, in allusion to its low melting point.
