This piece has 3 main crystals there is damage, but it wa sensual to see them so spaced out. Usually the crystals were much more tightly packed. What is more, the greenish matrix likely a mixture of fluorite and mica coating rock, adds a very interesting degree of contrast that is not seen on cassiterite samples from anywhere else.

13 Physical and Chemical Properties of Tin Every Chemist

T in does not occur naturally as the free element. In studying the properties of tin and its reactions, we must first examine the main source of this element which is the mineral called cassiterite or tin stone, SnO 2, which is found as low grade ore in alluvial deposits in Malaysia, Bolivia and Indonesia.

Definition – Cassiterite, also called tinstone, is a tin oxide mineral, SnO 2, which is the most important source of tin, and most of the world''s supply of tin is obtained by mining cassiterite is colorless when pure, but brown or black when iron impurities are present. Commercially important quantities occur in placer deposits, but cassiterite also occurs in granite and pegmatites.

In situ LAICPMS U–Pb dating of cassiterite without a

Cassiterite (SnO2), a main ore mineral in tin deposits, is suitable for U–Pb isotopic dating because of its relatively high U/Pb ratios and typically low common Pb. We report a LAICPMS analytical procedure for U–Pb dating of this mineral with no need for an independently dated matrixmatched cassiterite standard. LAICPMS UThPb data were acquired while using NIST 612 glass as a primary
