Basic Tools For Geologists

The close analysis of rocks, sediments minerals and other substances which are invisible to the naked eye are challenging tasks to the field mineralogists. If they are equipped with a portable hand lens, things will go easy and quick. Identification of the rocks and sands, the shape and size and sometimes their design are the common difficulties faced by them. Field trips and observations largely aid to identify the specimen, however, some minute features are often misinterpreted due to lack of a lens or magnifier.

The size and shape of fossils, crystals or even sand can be a hurdle when a large number of specimens is dealt at once. Many field workers use a hand lens and are seen tied around their neck or shirt pocket. There are also other tools that accompany them during their excavations into the dense world of mineral sands. Rock hammer, hand lens, camera, topographic map, field notebook, and Brunton compass are some of the tools that favour a geologist most commonly.

It easily slides into the pocket, opens the protected mode when not in operation, preventing scratches and ruins. It is handy, and weightless so as to tie the cord around the neck with a knot beneath the pivot hinge. The Kruss Pocket Loup is the most convenient tool among all glasses. It fits into the pockets, wallets or even in vehicles. It comes with the leather casket and also protected to reserve lens inside a desk drawer or bookshelf. It’s also 10x power glasses which finds application over extensive areas like gemology, jewelry check, printing, coin/stamp collection etc.

The soft leather lanyard from Gfeller is another tool where the lens is attached and can be easily worn around the neck. These help to prevent the risk of loss of keys, knife or lens.
