Inner Mongolia report

About since three years ago, some minerals that from north of China begin to appear in mineral market, in these minerals, the typical piece is Ilvaite, green quartz, arsenopyrite, hedenbergite, pink calcite, green global fluorite, red fluorite, green andradite etc. Some minerals crystal form and combination like another famous locality: Dal'negorsk, Russia. About the locality there are many story in these minerals. Go with the time advance, the real locality show itself bit by bit, these minerals are all from Inner Mongolia.

From spring of 2011, I went to Inner Mongolia many times for travel and purchase minerals, in the following article we will see a presentation of several locality that produce mineral specimens and some typical mineral specimen, hope it can help more mineral collector to know the minerals that from Inner Mongolia.

Rongguan Mine:


The Rongguan mine is located in the Daote Town territory of Dongwuqi(East Ujimqin Banner), the mine from the Banner government(Wuliyasitai town) 180 kilometers, from the Wuchagou train station 190 kilometers, 100 kilometers away from the Huolinhe City.

Google map:

Red 'A' is the frontier defensive road, green arrowhead point to the Rongguan mine.

From Erengaobisumu to Rongguan mine is a difficult gravelly road.

Traffic conditions:

From Linxi County to Rongguan mine by drive about need 7 hours, partly route is the frontier defensive road. The best route is: Linxi - West Ujimqin Banner - East Ujimqin Banner - Erengaobisumu - Rongguan Mine , main asphalt road and some gravelly road can up to the mine, traffic is convenient.

General interest:

The Rongguan mine is a large skarn polymetallic deposits, mining area covers an area of 2.4 square kilometers, the Rongguan mine was builded in 2004 by Inner Mongolia Xingye Group, and begin to produce at the beginning of 2006. Its major metal minerals include magnetite, hematite, limonite, sphalerite, pyrite etc...
