World marble rich in mineral resources , only exists on the local or
varieties of insufficient resources . World major marble producing countries
Italy, China , Spain, Portugal, Greece, Turkey, the Philippines , France, Brazil
, the United States , India, Austria, Russia and Japan . Resource-rich Italian
marble , fine texture , widely distributed , mining history, mining and
processing of advanced technology, is the world's most powerful marble resources
and producing countries , exports accounted for about half of total trade
international market , the " Card December December white " marble in the world
, known for fine marble varieties.
Portoro
Chinese marble rich in resources, color variety . As of end of 1996,
producing a total of 165 marble , reserves 1.084 billion m3, of which A + B + C
class reserves of 422 million m3.
In the past, China's long-term not as a separate marble mineral resources
be attached to the geological survey work base is weak, nearly 10 years as the
market demand and geological survey work unfolded, reserves increased rapidly,
but there are a lot of resources without geological survey work , no proved
reserves ; exploration and mining areas that have not been on in a lot of
development . According to the "96 China Mineral Resource Report" forecasts that
total resources of the country up to 20 billion marble m3, current proven
reserves account for only 5% of total resources .
China marble mineral only in the economically developed eastern coastal
regions and the geological survey has invested more work due to the overall
mineralization conditions are good , although the low level of exploration in
the past , so in the future according to market demand , as long as the
appropriate inputs , reserve growth potential greatly.
Second, the geographic distribution
China marble mineral lands in 26 provinces , autonomous regions and
municipalities are distributed, more balanced , only the relatively poor
northeastern region of proved reserves , accounting for 2.1% of the country's
total reserves ; South Central proved reserves most of the country's total
reserves of 33.2 % . Richest provinces of Guangdong, Hebei , Guangxi provinces (
district ) each have reserves of over 100 million m3; Shaanxi reserves of more
than 90 million m3; Sichuan, Beijing , Jiangsu, Zhejiang , Henan, Anhui, Guizhou
seven each province has reserves are more than 30 million m3.
According to the National Commission on Mineral Reserves criteria for the
classification scale deposits , marble deposits greater than 10 million m3 for
large , 200 to 10 million m3 of medium-sized , less than 2 million m3 for small
. China's existing medium-sized marble mineral mainly in Beijing , Hebei,
Jiangsu, Shaanxi , Zhejiang, Anhui , Sichuan, Hunan , Jiangxi, Yunnan, Guangxi,
Guangdong and other places .
Third, the characteristics of resources
( A ) color than the whole, wide variety, has formed a series
China has been found in more than 400 varieties of marble major , even
Italy marble industrially developed countries in this regard can not be compared
. The trade numbers , you can bulk exports have more than 100 kinds of marble
.
A variety of colors , patterns , marble has formed a series , white, black
, red, gray, green , yellow, pink , color and taste. Patterns are cloudy,
landscapes shaped , threaded , willow , star porphyritic and rare fossils
patterned so on everything .
( Two ) quality is better, the vast majority of the market selling Chinese
marble varieties of good quality , fine texture, elegant colors , beautiful
patterns , gloss , decorative performance, performance can meet the relevant
standards . Many varieties in the domestic market welcomed by the users , has a
certain reputation . Such as white series of the Beijing Fangshan, Hebei Quyang
"white marble " Baoxing of the " Shu white " , Yunnan Dali " Cangshan white" ,
Yunnan Yuanyang " Yuanyang crystal white ", Shandong Laizhou " Snow White "and
so on ; black series have Bijie " Crystal Moyu " Hunan bimodal " Twin Peaks
black " , etc. ; red series , Anhui Lingbi " red Anhui Lo " , NANJIANG of the"
South River red " , Liaoning Tieling " Tieling red" , Hebei Laishui " laishui
red" , etc. ; gray series of Zhejiang Hangzhou " hang Grey " Dali "cloud gray ",
Shandong Laizhou " of ash" , etc. ; green series Dandong in Liaoning " Dandong
green ", Shandong Laiyang " Laiyang green " , Henan Lushan 's " Lushan green " ,
etc. ; yellow series Henan Xichuan " rosin yellow ", " beige " , Guangxi
statewide " wood yellow " , etc. ; flesh there Jiangsu Yixing " red butter ","
white butter " , Guiyang 's " pattern fat butter "and so on . With beautiful
pattern known varieties in Hubei Huangshi , " fragrant ", " turtle bi ", " Jin
Huang ," Beijing Fangshan " Ai Ye ," Dali "cloud flower" , Shaanxi Tongguan "
Jade Dragon " , Shanxi wenxi of the " waves ", " autumn ", etc.
( Three ) Proved Reserves stone varieties to mid-range , high-grade less
like " marble ", " Dandong green ", " Rosin yellow" and other famous welcomed by
merchants , but due to less reserves , mining for a long time , has been
difficult in large quantities mined. Especially in international markets sold
briskly white , pure black , light-colored marble resources in terms of quantity
, the quality is still inadequate.
( Four ) parts quality marble deposits in remote mountainous areas, there
are great difficulties in the current development of southwest China there are
many high-quality marble deposits, but in remote mountainous areas, high
mountains, dangerous mining conditions are poor , especially transport costs
over high in the short term is difficult to scale development . Clouds Nanfu
Gong 's " snow Chui ," Yuanyang " Yuanyang crystal white ", " Yuanyang Ice "
Pingbian " Pingbian white" ; Sichuan asbestos " white asbestos ," Oscar 's "
marble " , etc. .
