Chinaese reserves of granite state

As decorative stone, the color of granite and rock timber requirements are higher, so the output is not more famous granite country. Because granite is a large mineral resources, most of the demand side of local exploration or mining exploration side, less for large-scale geological survey work advance, so No mineral resources and reserves of the world's granite statistics reported.
    (A) Granite Tile mineral resources China's position in the world
Granite from around the world production and import and export analysis, China, India, Brazil, South Africa, Spain, the former Soviet Union, France, Korea, Finland, Norway, the United States, Italy, Portugal, Germany and other countries all have rich mineral resources of granite. China is the world's most powerful resources and producers of granite, just in terms of production and export of granite over Italy, ranking first in the world.
    (B) Chinese Granite Slab mineral reserves
Igneous and metamorphic development of Chinese deep wide, vast distribution area, granite mineral resources throughout the country. As of the end of 1996, granite mineral 297, in addition to Shanghai, Tibet, widely distributed in the provinces (autonomous regions and municipalities), to maintain total reserves of 1.709 billion m3, which finishes with a total of 161 mineral deposits of granite, to maintain reserves of 950 million m3, of which B + C-class reserves of 338 million m3. Finishes with granite mineral reserves shown in Table 4.24.7.
Proved reserves at the origin of granite rock types are granite, gabbro, diabase, peridotite, diorite, tuff, serpentinite, amphibolite, basalt, pyroxenite, etc., which overwhelmingly dominant granite position, proved reserves of 63.42% of total reserves.
(C) the amount of mineral resources in China granite
China complex geological conditions, period of time than tectonic movements, magmatic activity frequently, granite provides a very broad mineral prospecting. Granite deposits are divided into magmatic and regional metamorphic granite deposits of granite deposits in two categories. Magmatic deposits in the major geological units are distributed, formed in the Precambrian, Caledonian, Hercynian, Indo-China, Yanshan and Himalayan such period, including Yanshan and Hercynian granite deposits in the most widely distributed; Regional metamorphic deposits are distributed in North China Platform area, mineralization in the Archean period, the main ore body exposed area, into the film into with the distribution of lithology mostly acidic or alkaline or potassium of migmatite granite series. According to the "'96 China's mineral resources report" incomplete statistics, China's total mineral resources of granite is about 230 to 240 billion m3. Current proved reserves account for only 4% of total resources.
Chinese granite mineral only in the economically developed eastern and coastal areas into a more geological exploration work, due to the overall good mineralization conditions, low levels of exploration in the past, so in the future based on market demand, as long as the appropriate investment, reserves, resources are still significant increase in potential.
