www.letstonesspeak.wikispaces.com COLLECTING ROCKS AND MINERALS Starting a collection Most collectors begin by just accumulating rocks, minerals, fossils. As their collection grows, they start being more selective, keeping only specimens with better colour, better crystallization, or more interesting crystal forms. With widening experience, most collectors begin to specialize. Some minerals come in such a wide variety of crystal forms that a collection can be made of a single mineral; other collectors may focus on ore minerals, or on minerals from a particular locality. There are practical considerations that limit the scope of most collections. Some rare minerals are very expensive, and mineral collections can take up a huge amount of space. One solution is to collect tiny specimens called micromounts, whose form and beauty can only be seen under magnification. ESSENTIAL EQUIPMENT At first glance it might seem that any hammer would do for breaking rocks, but this is far from the case. Every year rocks collectors are injured – including being blinded – by using the wrong hammers. Geologist´s hammers are made of special steels, and the striking ends are bevelled to prevent steel splinters from flying off them. Special geological chisels are made for the same reasons. Wearing safety goggles is highly recommended when breaking or splitting stone. Access to some collecting localities requires safety equipment such as a hard hat and fluorescent vest. A mobile phone is an important piece of safety equipment – with fully charged battery. Carry it with you even if you are only going a short distance from the car. A fall into a ravine or other low spot may take you out of sight of potential help and add hours to the time it takes to find you. In desert country, an adequate supply of water is essential, and if you are in snake country take an appropriate snake-bite kit. Clothimg suitable to the weather and terrain is, of cours, vital. Leave your low- www.letstonesspeak.wikispaces.com cut shoes and trainers at home. Leather boots offer better protection from snake bites, cactus spines, sharp stones, jagged metal, and rolling stones, and give much better traction. COLLECTING SAFELY While mineral collecting is generally a safe hobby, there are a few definite hazards that he collector needs to be aware of. The most dangerous collecting locality is around old mines and workings. Tunnels should never be entered – shoring timbers rot verry quickly, and cave-ins and rockfalls are almost guaranteed to happen. In any case, there is often remarkably poor collecting inside old mines. If anything looked good, the miners usually dug it out. Mine dumps, by contrast, can be a good source of specimens, although be aware that they are often loosely piled and can be unstable. When collecting in localitions such as beach cliffs, road cuttings, and rockfalls, attention must be paid not only to loose material underfoot but also to anything that may fall or roll from above. Collectors are injured every year by falling rocks. And, unless you absolutely know the locality to be safe, leave small children at home.
