| 31. | In 1987 cassiterite ( tin ore ) crystals in a stream in the Taurus foothills were found by the MTA geologists.
|
| 32. | Tin Creek and Cassiterite Creek, about south of Brooks Mountain, have tin ore deposits in tourmaline and garnet rocks.
|
| 33. | A few other minerals are also closely associated to chatkalite based on locality, these are cassiterite, hermisite and hessite.
|
| 34. | These are cassiterite-silicate ore units of cassiterite-tourmaline mineral type, similar to other deposits in the district.
|
| 35. | These are cassiterite-silicate ore units of cassiterite-tourmaline mineral type, similar to other deposits in the district.
|
| 36. | Cassiterite is usually black, purple or otherwise dark in color, and these deposits can be easily seen in river banks.
|
| 37. | Because of the low concentration of cassiterite in an alluvial deposit, large quantities of material must be handled in recovering it.
|
| 38. | Cassiterite, platinum, scheelite, allanite, and native bismuth have been recovered along with gold from placer mines in the district.
|
| 39. | The chief tin producing centre in China was the Kochu district in Southern Yunnan where cassiterite was obtained from deposits and rock ores.
|
| 40. | Cassiterite ( SnO 2 ), the tin oxide form of tin, was most likely the original source of tin in ancient times.
