(B) picking stone starting stone industry

In the late 1970s, the Tianjin Import and Export Corporation sent a large crane in Hunyuan Nanshan (Hengshan) river bank lifting boulders, the kind of green 1 ~ 3 meters in diameter of the huge stone, a few pieces of loaded trucks to pull away. Later, local villagers realized that it was green granite (trade name), can be cut and ground out of grass-green plates exported to Japan, is used for tombstones. At the beginning of the village to charge them, each hanging away from a piece of raw stone to charge a few dozen dollars. When the river bank within 100 miles of the big stone hanging all, began to develop the mountain native green stone. It turned out that they are 2 billion years ago from the depths of the mantle along the crustal fissure invasion, this iron rich magnesium rock called pyroxene, it is invaded in the 1.9 billion years ago after regional metamorphosis formation. Hunyuan's stone mining and processing industry also emerged from its existence.

In the early 1980s, these green metamorphic pyroxene was extracted, began to extract black granite (trade name). They are unmetamorphosed gabbro intruded 1.6 to 1.8 billion years ago and are widely distributed in Hengshan. Large and small stone factories, grinding and cutting slate processing plant, such as the development of the spring in Hunyuan, and soon spread to Yingxian, Fanchi, Daixian, Lingqiu counties. These pyroxene are 5 ~ 20m wide, extending a few kilometers to more than a dozen kilometers, upright wall-like, along the direction of the north west 315 ° ~ 340 ° stretching distribution.

Yuxian pyroxene stone

Hengshan building materials and minerals from the beginning of the development of pyroxene, one after another in the Lingqiu Nanshan found "Guifei red" granite, found in Daixian duromorphite, a large purplish-red garnet aggregates and slabs of translucent amphibole - straight amphibole as a background of high-grade finishing stone.

In the early days of reform and opening up, driven by the Shanxi Provincial Import and Export Corporation, Wutaishan green schist, Dingxiang gray-purple slate, Taihang Mountain red sandstone slabs, are not polished just cut and molded, can be exported. To the 80s of last century, Shanxi rise plate heat, Lou trouble Wulongshan marble mine, Guangling six prismatic marble mine, Wutai Dongye marble plant, Yu County five open palm marble mine, Ningwu, Wuchai Zisu granite mines, Lincheon, Wenshi marble mines are booming, from Shanxi into the stone industry booming period.
