Basic Introduction of Songhua Stone

Songhua Stone, also known as Songhua Jade, is a marine mudstone sedimentary rock produced in the Changbai Mountain area of northeastern China. Songhua stone is a hard sedimentary microcrystalline limestone formed by the sedimentation, covering, and compression of fine mud on the seabed during the marine movement hundreds of millions of years ago. The basic mineral components are calcite, quartz, mica, clay, and a small amount of metallic minerals

Due to the influence of geological factors within the region, as well as the quality of metal ions and pigments in residual minerals after marine biological decay, stones in a small area exhibit different colors. Generally speaking, yellow turquoise has a higher content of divalent iron, while red turquoise has a rich content of trivalent iron; The manganese and iron content in purple turquoise is more prominent; The elements of chromium and copper in green turquoise are relatively high. Gray colored Songhua stone has a high proportion of territory and talc content, while black colored Songhua stone is a mixture of sulfur and iron minerals. Moreover, due to the phenomenon of ocean currents on the seabed, it drives the movement of viscous sea mud, which covers the original seabed in a layered form, forming a multicolored band pattern of turquoise. This type of turquoise is highlighted by purple and green bands

The main mineral resources are distributed in the Changbai Mountain area of Northeast China, especially in the areas of Tonghua, Baishan, and Yanbian, which have excellent color, large reserves, and sustainable mining. The Benxi area of Liaoning and some areas of Anhui also have marine sedimentary rock deposits, but the texture is relatively rough. The color of Songhua stone mainly includes three color series: solid color series, symbiotic color series, and associated color series

1. The main solid color series of Songhua stone are green, cyan, yellow, brown, and purple. There are also rare colors such as black, red, and white

2. Symbiotic color schemes mainly include two-color schemes such as yellow green, purple green, and purple yellow green, as well as tricolor and multi-color schemes

3. The associated color system is a special type of stone formed by the inclusion of larger particles of barite, jade, quartzite, and other materials during the mud sedimentation process, such as star and moon types formed by the inclusion of barite, and ice patterned types embedded with striped water crystals

In the color of Songhua stone, Yang green is the top grade, chestnut yellow is the premium, and maple red is the rare. Others are also authentic products with pure and bright colors. Of course, in the multi-color series and companion color series, as long as they are harmonious and vivid, they are also excellent materials
