PANTOM INTERNATIONAL FREIGHT FORWARDERS CO ., LTD Customs Commissioner: Miss Xie DG Address: South City New Year new base Avenue Block A, 3rd Floor 1329-1331 Hong Kong-based wisdom extended reading; Sandstone: formed from quartz grains (sand), structural stability, usually in the form light brown or red, mainly silicon, calcium, clay and iron oxide. 3 sedimentary rocks belong. Soapstone: formed from a variety of talc, very soft. It is abrasion resistant mineral dense and difficult to produce stains. 4. Fossils: with marine shellfish, natural plant fossils, is considered to be limestone. 5. Travertine (Ulva): Travertine? Usually cream-colored or reddish, calcite deposited by hot springs. Because the flow through from the stones and the formation of many small holes, these holes used synthetic resin or cement filled, otherwise require a lot of maintenance work. Are limestone and marble. Second, metamorphic rocks under high temperature and high pressure mixing and minerals from natural deterioration of a stone into another stone. Qualitative change may be recrystallized texture change or color change. 1. Marble is recrystallized limestone, limestone softened under high temperature and pressure, and changes during re-crystallization of minerals contained in the formation of marble. The main component is calcium and dolomite, many colors, usually with distinct patterns, many mineral particles. Mohs hardness between 2.5 to 5. Marble divided into three categories: Dolomite: magnesite (magnesium carbonate) content of more than 40% of forsterite: magnesite (magnesium carbonate) content of 5% to 40% between. Calcite: magnesite (magnesium carbonate) content of less than 5% 2. :( Bluestone slate shale, yellow wood ??) by clay rocks, sedimentary shale (sometimes by metamorphic quartz) formation of fine mineral particles, thin and fragile, usually black, gray or green. 3. Its like a snakeskin pattern serpentine named, the most common color is green and brown. Mohs hardness between 2.5 to 4. Contain large amounts of magnesium, from igneous rocks. Recrystallization and diamond polishing effect is sometimes poor. Third, mainly formed by volcanic igneous igneous material, such as magma. Subsurface liquid magma cooled, solidified. Minerals, gas and liquid into the rock to form a new crystal and a variety of colors. 2, Granite:
