同时，该局联合湖北省地质局等单位，通过统筹部署与协同攻关，聚焦鄂西恩施二叠系页岩层系，成功 实现工业气流突破，开拓了非常规气新层系新类型，实现了页岩气勘探从四川盆地向鄂西地区的有效拓 展。该成果形成的成藏理论认识和高效返排技术，将对复杂构造区页岩气勘查部署产生重要指导作用， 具有显著的理论价值与工程实践意义。 记者近日从自然资源部中国地质调查局获悉，我国矿产资源勘查又有新进展，铬铁矿与非常规油气勘查 均获新突破。 铬铁矿是我国紧缺战略性矿产，主要用于冶炼含钴、镍、钨等元素的特种合金。它也是航空、航天、汽 车、造船等领域不可或缺的材料。据介绍，自然资源部中国地质调查局联合新疆维吾尔自治区自然资源 厅，在新疆萨尔托海南矿带覆盖区开展铬铁矿找矿勘查，新发现萨尔托海27矿群，圈定矿体20个，平均 品位30.73%，实现该地区近40年来最大找矿发现，为"十四五"铬铁矿找矿目标任务完成提供了有力支 撑。 ...

Core Viewpoint - The recent breakthroughs in chromium ore and unconventional oil and gas exploration in China mark significant advancements in mineral resource exploration, contributing to national strategic goals and economic development [5][10][31]. Group 1: Chromium Ore Breakthrough - A major discovery of the "Sartohai 27 mineral group" has been made in the Sartohai area of Xinjiang, with 20 mineral bodies identified and an average grade of 30.73%, representing the largest chromium ore discovery in nearly 40 years in the region [18][31][35]. - The innovative exploration techniques employed include a comprehensive combination of "rock type zoning + alteration zoning + structural" markers, significantly enhancing the identification of deep concealed mineral bodies [31][35]. - The new findings have redefined the understanding of mineral-bearing rock types in the Sartohai area, with 11 chromium ore bodies found in carbonate ultrabasic rocks, accounting for 70% of the newly discovered ore resources [32][35]. Group 2: Economic and Strategic Implications - The breakthroughs in mineral exploration are crucial for enhancing China's self-sufficiency in key strategic minerals, which are essential for industries such as stainless steel, special alloys, and high-end manufacturing [32][35]. - The successful completion of the "14th Five-Year Plan" mineral exploration goals is supported by these findings, which are expected to bolster the high-quality development of resource-rich regions in western China [18][31].
