PAGE 10 TERRACE HERALD, TERRACE, B.C. MONDAY, MARCH 22, 1971 [Prospectors cor MINERALS All rocks are made up of minerals. A mineral is a natural solid, inorganic substance which has a definite chemical make-up, form, and set of characteristics. We can therefore identify each mineral by applying some very simple ‘field tests’. There are over 1,000 known minerals, In practical prospecting, however, we are concerned with a smali percentage of these. In order to identify minerals, one should have a good pocket- knife, a mineral lens of about 10 power, and piece of quartz with a smooth side. OBSERVATION Identification in the field is done by cbservation of the effect of various tests and of the appearance of the mineral specimen itself. | Hardness, weight, color, streak, crystal Structure, fracture, cleavage and odor are all taken into consideration when determining the name or identity of the mineral in question. A list of minerals with their corresponding characteristics can be oblained in any good dealing ‘vith minerals or prospecting. Two good books of low price are as follows: - How to know the Minerals and Rocks, by Richard M. Pearl, 75c. - Elementary Geology Applied to Prospecting by D.M. Walker, 65c. The first book can be obtained from most book stores, the latter is obtained from the B.C. Department of Mines, Victoria, or can be ordered from the ‘Northern B.C. Chamber of Mines, P.O. Box 668, Terrace. In the next few items appearing in ‘Prospector’: Corner, " we shall deal with identification of minerals. The first field test is: HARDNESS This is determined by scratching the specimen with something of which - the hardness is known. If the specimen is scratched, it is therefore softer than the object being used, if the specimen will not be seratched, then the specimen is harder and a second scratch should be attempted using an object of greater hardness. From the table of hardness below, you can see that the fingernail, a copper coin, a good knife, a piece of quartz, a file, and common glass are all used to determine hardness. The scale of hardness was devised by a Fredrick Mohs, over 100 years ago, and is known as the ‘Mohs Scale’. Each number refers to the known hardness of the object or specimen listed, a hardness of 8 for instance is not necessarily _ twice as haad as a hardness of 4. HARDNESS SCALE 1, Tale; 2, Gypsum; 21a, fingernail: 8, Caleite; 4, Flourite; 5, Apatite; 5 Goad pocket-knife: 5142, common glass; 6, Feldspar; 7, Quartz; 8, Topaz; 9, Corundum: 10, Diamond and 3, Copper coin.

The difference in hardness between these two minerals-is much greater than that belween any other two minerais on the scale lying adjacent to each other.
