案例:西部某省L县地处彝岭南部,黄金资源比较丰富.2005年4月,一支淘金队来到该县G镇干河坝村,在嘉陵江支流干素河的河道边上淘金.群众举报后,L县国土资源局认为,根据省政府2004年颁布的第100号政府令,河道内采砂、取土、淘金的监督管理权在水利部门,自已不是主管部门,不应对此事负责.L县水利局认为,该淘金队超出了河道范围淘金,不属于自已的管辖权限.就这样,淘金队的行动畅通无阻.直至2006年2月,被新闻媳体曝光后才停下来. 相似文献

2011年5月27日,一部小制作影片《狗头金》悄然上映。影片的内容很简单,也很老套,主要讲述了5个穷困潦倒的淘金汉子,为了各种目的,冒着种种危险结伴进山淘金。 相似文献

At peak granulite-facies metamorphic conditions, lower continental crust is arguably fluxed by large amounts of two key low water activity fluids: (i) high-density CO2 and/or (ii) concentrated saline so- lutions. These fluids are either internally-derived, generated by mineral reactions or dehydration melting or, notably for CO2, externally-derived, issued from the underlying mantle. Postmetamorphic evolution results in complete disappearance of these fluids, except for minute remnants preserved in minerals as fluid inclusions. Two major processes are involved: (i) at peak conditions, granitoid magmas form, migrate upward, and crystallize as shallow intrusions in the upper crust (mineralized porphyry types or reduced intrusions); (ii) during the rapid decompression which almost systematically follows a period of post-peak isobaric cooling, especially for ultrahigh-temperature granulites (anticlockwise P-T paths), quartz-carbonate megashear zones are formed by repeated periods of seismic activity. Seismic activity may continue until all free fluids have disappeared, resulting in the ultramylonites and pseudotachylites that are found in many granulite domes. A great majority of vein-type Au deposits worldwide occur in the above-mentioned settings or nearby. We suggest that the Au has been scavenged by the granulite fluids, then redistributed and concentrated during the formation of veins and related phenomena. 相似文献

自1848年美国加利福尼亚州北部最早发现黄金起,仅仅1年后,来自全世界的淘金客就达3万人,这使得原本荒凉静谧的原野,一夜之间蜕变成热闹喧嚣的小城,金主、探险家、商贩甚至抢匪与流氓,各色人群云集于此,翻地掘土并把泥土放进筛子里摇晃,来得到这些能让他们过上幸福生活的金属. 相似文献

今年3月以来,浚县国土资源局采取有效措施,在全县强力推进对废弃矿石堆筛选翻捡,提高矿石利用率活动。各采矿户积极响应,并掀起废弃矿石堆中“淘金”热。据不完全统计,目前,该县已有12家采矿户回选矿石8500立方米,收入近4万元。全县呈现出杜绝采富弃贫、提高开采利用率的新气象。 相似文献
