Rhodochrosite is a kind of manganese carbonate mineral and belongs to the trigonal crystal system. The crystals are rhombohedrons and are often produced as aggregates. They are granular blocks, melkerig, stalactites, nodules, and nodules with concentric layered patterns inside. It has glass luster to pearl luster, deursigtig tot deurskynend, hardheid 3.5-4.5. The color of rhodochrosite [...]

Die hoofkomponent van kassieriet is tinoksied, wat 'n oksiedmineraal is, wat dikwels spoorelemente soos yster bevat, niobium, tantaal, titanium en mangaan. Cassiteriet is 'n tetragonale kristalstelsel. Die kristalle is dikwels kort kolomvormig, skraal kolom- of dubbelkegelvormig, en die koniese aggregate is blok, korrelvormig of niervormig; with diamond luster to [...]
The main component of rutile is titanium oxide, which belongs to the oxide minerals, dit is, it is a homogeneous and multi-image variant with anatase and brookite, and constitutes the rutile family. Rutile belongs to the tetragonal crystal system, the crystals are columnar, biconical or needle-shaped; they have diamond luster to semi-metallic luster, transparent to [...]
Apatiet is 'n kalsiumfosfaatmineraal met 'n komplekse chemiese samestelling, wat dikwels cerium bevat, uraan, torium en seldsame aardelemente. Volgens die verskillende bykomende anione, dit word in fluorapatiet verdeel, chloorpatiet, hidroksiapatiet en Daar is baie variëteite van strontiumapatiet ensovoorts. Hulle het 'n soortgelyke verhouding met mekaar, and fluorapatite is usually [...]
Kyaniet, whose English name is Kyanite, is derived from the Greek Kyanos, wat beteken "blou". It also has another English name, Kisthene, which also comes from Greek, wat beteken "double" en "krag". It refers to different hardness. It shows one of the biggest characteristics of kyanite, dit is, the product is in different directions on [...]
Ioliet, wie se Engelse naam Iolite is, kom van die Griekse woord, betekenis "violet", wat die edelsteen-vlak kleur eienskappe aandui. Dit het ook verskeie Engelse name, een daarvan is Cordierite, vernoem na die Franse geoloog wat die mineraal die eerste keer in die 19de eeu beskryf het, Pierre Louis Dental Die (PLcordier); die tweede, Dichroite, ook uit In Grieks, [...]
Hemimorphite is a silicate mineral with zinc as the main component. Dit bevat 53.7% zinc and sometimes contains a small amount of aluminum and iron. It is an important mineral of metallic zinc, and only a few colorless and transparent crystals are used as gems. Hemimorphite belongs to the orthorhombic crystal system, and the crystals [...]
Piriet, die Engelse naam Pyrite, kom van Grieks en beteken "vonk", omdat hierdie mineraal vonke uitstraal wanneer dit deur harde voorwerpe soos staal getref word. Omdat die oppervlak van piriet geelbruin is, dit het 'n sterk metaalglans op die kristaloppervlak of gepoleerde oppervlak, en word dikwels met goud verwar, so word dit ook genoem [...]
The staurolite is a hydrous silicate mineral of aluminum and iron. It belongs to the monoclinic or pseudorhombic crystal system. The crystals are well developed and are short columnar. They usually have a cross with an angle of 90° or an X with an angle of 60°. Shape through the double crystal. The staurolite has [...]
Epidote is 'n soort hidriese kalsiumaluminosilikaatmineraal met eilandstruktuur. Omdat die samestelling daarvan dikwels verskeie spoorelemente soos mangaan bevat, magnesium, chroom, natrium en kalium, daar is baie soorte soortgelyke plaasvervangers, soos Dit is ryk aan mangaan as monedriet, chroom is vervat in chroom epidoot, and calcium is replaced by [...]
