What reading level is Handbook to the Mining And Geological Museum Sydney book?
To quickly assess the difficulty of the text, read a short excerpt:
Hardinge: granite traversed by very conspicuous veins of black tinstone.
1562-3 and others from the Giant's Den Mine, Bendemeer. The ore here occurs with quartz in greisen, and is interesting from its association with tourmaline. 1562 shows radial groups of dark-green tourmaline. T * On the presence of wolfram in tin ores see page 72.
t Tourmaline can be distinguished from tinstone by (a) not being so heavy (specific gravity about 3 only) ; (fy frequently occurring in bundles of needle- like cr...ystals; (c) crushing to a greenish powder; (rf) being easily fused before the blowpipe.
71 165, in case 126, is tinstone that has replaced some other Case 64. Mineral probably calcite while still preserving the original crystalline form of the latter (pseudomorphous replacement).
4193, in case 126, is a large specimen of crystallised tinstone from New England.
While New England is the principal tin-field, tin ores are found in many other localities.
In the West, tin has been found at Eremeran, in the Cobar western district.
