Abstract

Изобретение относится к области прикладной геохимии и может быть использовано при поисках месторождений полезных ископаемых, при прогнозно-геохимическом картировании закрытых и полузакрытых территорий на основе данных геохимического картирования исследуемых территорий и последующего анализа проб почв. Положительный результат достигается сгущением сети опробования (особенно при поисках мелких и средних золоторудных объектов), отбором проб горизонта B1 почвы весом 50-60 г, из которой приготавливают суспензию и из нее выделяют тонкодисперсную фракцию с размером частиц 2-35 мкм и весом 2-3 г, которую высушивают при комнатной температуре не менее 24 ч. Сухую тонкодисперсную фракцию наносят на стеклянную палетку размером 12×10×0,3 см в количестве не менее 200 квадратов, помещают в них полученные сухие тонкодисперсные фракции проб, которые анализируют на редкие элементы методом лазерной абляции, после чего по содержанию в них химических элементов строят карты их распределения по площади и выявляют на картах зоны аномальных содержаний индикаторных элементов, по которым определяют наличие зон рудной минерализации, рудных тел и месторождений редких элементов.The invention relates to the field of applied geochemistry and can be used in the search for mineral deposits, in forecasting and geochemical mapping of closed and semi-closed areas based on geochemical mapping data of the studied territories and subsequent analysis of soil samples. A positive result is achieved by thickening the sampling network (especially when searching for small and medium-sized gold ore objects), sampling horizon B1 of soil weighing 50-60 g, from which suspension is prepared and a fine particle with a particle size of 2-35 μm and a weight of 2-3 is isolated from it g, which is dried at room temperature for at least 24 hours. A dry fine fraction is applied to a glass palette measuring 12 × 10 × 0.3 cm in an amount of not less than 200 squares, and the resulting fine finely divided fractions of samples are placed in them, which are analyzed and rare elements using laser ablation, after which the content of chemical elements in them build maps of their distribution over the area and reveal on maps the abnormal contents of indicator elements, which determine the presence of ore mineralization zones, ore bodies and deposits of rare elements.
