Shandong purple sandstone and its mineral introduced

 

Shandong purple sandstone Profile

 

 

 

    Shandong purple rock is mainly purple bottom with subtle white granular textured sandstone, uniform and stable color tone seemed solemn wealth, harmony and texture, the color difference is not small part partial color mauve or beige.

    Shandong purple rock produced Junan County Shandong southeast coast, is a marine sandstone structure relatively coarse particles, the hardness is relatively large, close to the hardness of granite. And is located in the plains, mining conditions can aniseed currently produced 3 m X2 m large plate blocks, also can supply special size blocks. However, because of the constraints of local equipment and processing technology, the main supply of 80-90cm plate, large plate or 1.2 or 1.4 meters above the Fujian head processing, but a small part of the plant is able to produce a large plate of 1.2 meters, but the unit price than high.

    Shandong purple rock surface finish of polished, matt, lychee, chisels, sandblasting, natural surface, and can also engrave which do relief better, but Sichuan sandstone carving performance is not enough delicate. Shandong purple rock hard material, mainly used for walls, flooring, outdoor and garden stone, can also be used as the exterior curtain wall decoration.

Shandong purple rock deposit conditions

 

 

 

Geological profiles:

    Ore body to the the the Cretaceous Holtek Tian floor Formation, the orebody morphology of irregular polygons, the ore body is simple, blocky, completeness, minerals evenly distributed organizational structure is dense and hard ore The joints are not developed, blocks out into a higher rate.
