| New Findings and Perspective Analysis of Prospecting for Volcanic Sedimentary Boron Deposits in the Tibetan Plateau |
| This paper reports the new achievements in the prospecting for volcanic sedimentary boron deposits. The presence of strata of boron-rich volcanic sedimentary binary structure in the Tibetan Plateau was discovered and confirmed for the first time. The tectonic location, stratigraphic combination and the age of the strata are consistent with features of the strata of the large volcanic sedimentary boron deposits in Western Anatolia plateau. The strata have positive high anomaly of rare alkali metal elements, and boron element content has reached ore cutoff grade in some intervals; in addition, crumbly or banded borate minerals were found. These discoveries show that the Xiongba basin has the geological, mineral and geochemical prerequisites of the volcanic sedimentary deposits, and possesses the potential of large deposits. This discovery belongs to the basic superior result in the search for volcanic sedimentary boron deposits in China, which provides important scientific basis for the discovery of this type of boron deposits in the Tibetan Plateau. |
