矿产预测中成矿信息的提取和强化

成矿信息的提取是矿产预测的重要手段,其方法的有效性直接影响到预测成果的可靠性。在成矿规律研究的基础上,有意识地干预模型的构成,突出与成矿有关的信息;抑制某些成矿意义不明显和属干扰的信息,有目的地使模型向反映成矿信息的方向逼近,提高模型与矿床实际赋存地质环境的吻合程度,均是成矿信息提取和强化的内涵。本文从研究实践中总结了先验约束模型和非先验约束模型的强化方法,在新疆阿勒泰地区的地质－找矿工作中已取得     

Intrinsic sample methods for mineral exploration and resource assessment

We report on an objective methodology, referred to as intrinsic sample methodology, for the delineation of exploration target areas or resource areas for assessment. Important features of the methodology include (1) identification of recognition criteria for critical genetic factors, (2) synthesis of new variables from enhanced geodata, (3) estimation of logit probability models, and (4) cutting of estimated logit probabilities to delineate exploration targets or resource areas. The methodology is demonstrated on the Walker Lake quadrangle of Nevada and California.     

碳中和目标下关键矿产在清洁能源转型中的作用、供需分析及其建议

在"碳中和"目标的驱动下，全球能源系统向清洁化、低碳化甚至无碳化发展已是大势所趋。针对向清洁能源转型的需求，采用了统计对比、分类汇总、综合分析等方法，分析研究了关键矿产在电池、电网、低碳发电和氢能等行业中的作用和需求。结合当前关键矿产产量的地理集中度高、项目开发周期长、资源质量下降等矿产供应和投资计划不能满足清洁能源转型的需求等问题，提出确保关键矿产多样性供应，推动价值链各环节的技术创新，扩大回收利用，增强供应链弹性和市场透明度，将更高的环境、社会和治理标准纳入主流程及加强生产者和消费者之间的国际合作等建议。     

重视和加强岩矿物性的测量研究

本文从物探科学技术的进步,勘查任务的发展变化、物探方法应用范畴的扩大和物性勘探等几个方面,论述了岩石和矿物物理性质测量、研究的重要性,指出：物性工作不可能毕其功于一役,并提出了五点建议：１．深入研究各类矿藏及其围岩（直至地面）物性的空间变化规律,为选择、研究合适的物探方法,提高物探效果,进一步探讨“直接”找矿问题,提供依据;２．这项工作可专门进行,但最好尽可能利用为其他目的而设计的钻井进行;３．物     

我国勘查地球物理的若干进展─1994年

1994年,我国固体矿产地球物理工作仍不景气,水文、工程、环境地球物理市场平稳,油气地球物理工作持续增长.陆上三维地震年工作量首次超过一万平方公里.高山、大沙漠地区三维地震采集创造成功经验,地震数据全三维处理、解释技术和软件系统的研究和应用取得显着进展.航空地球物理工作量略有回升.总体上1994年我国各类勘查地球物理方法在“硬件”(仪器设备)方面的新进展相对较少,而在“软件”(方法技术特别是数据处理、解释技术)的研究、应用方面则取得较多重要进展.     

我国藻菌生物成因的金矿研究

生物成矿作用分为生物直接成矿作用和生物间接成矿作用,生物直接成矿作用的标志结构为生物有机胶体结构。生物间接成矿作用的标志结构为“矿交代生物”结构,我国陕西二台子－半仓沟金矿,四川东北寨金矿、川甘拉尔玛金矿和云南金厂金矿等均为典型为实例,矿石中普遍含有多种金属矿物生物结构,还含多种生物有机组分。成矿物质具有多源性特征,硫同位素具混合型特征,矿床成型机制可与“人工碳吸附系统”聚金机制相类比,含金层位可     

Possible ways to decipher spatial distribution of mineral resources

Regularity of structural patterns can be connected to planetary disjunctive systems (paleosystems). A computerized universal model of these systems should be developed that may be helpful to predict unknown localities of mineral resources controlled by tectonic processes. The specific character of tectonic phenomena is to be respected in geomathematical models. Some suggestions for applications are given.     

综合利用地震多参数预测油气藏

以吉林省境内红星构造带(已发现油田)和杨柳青构造带(未发现油田)为试验区,首先利用地震地层学方法,研究间接参数特征,确定有利相带和有效圈闭,并在有效圈闭上选择了39个2×2cm时窗。在时窗内提取与地震波动力学有关的信息,即频率、振幅、频谱能量等,然后对这种信息进行统计计算,获得振幅方差等九个参数并对其进行综合分析,从已知油气藏出发,对未知圈闭油气状况进行了三级预测,指出了最有利的勘探靶区。     

Catalytic ozonation of phenol in water with natural brucite and magnesia

Catalytic ozonation has attracted much attention in treatment of wastewater for its mild conditions. Phenol and its ramifications are common components in a wide variety of wastewaters including those from coal conversion processes, coking plants, petroleum refineries and several chemical industries. In this paper, natural brucite and magnesia have been successfully used in catalytic ozonation of phenol. And the mechanisms of catalysis were also investigated. From Figs. 1 and 2, it can be found that both brucite and magnesia have remarkable catalysis on degradation of phenol and removal of Chemical Oxygen Demand （COD）. The pH of solutions on the process of ozonation alone, catalytic ozonation with brucites and with magnesia were 6.35-2.76, 10.18-8.52 and 10.58-10.83, respectively. It can be concluded that alkali environment plays a critical role for catalytic ozonation of phenol. We also found that the alkaline minerals reacted on the surface with oxalic acid and other low molecular-weight acids which are intermediate products in ozonation, but those intermediate products could be mineralized into carbon dioxide completely with enough ozonation time.
