摘要

问题的相关性。彼得罗夫斯基矿床是一个有希望开采磁铁矿的地区。上世纪80年代对该矿床进行了详细的研究,但随着矿坑的加深和扩大,以往的研究数据已失去了相关性。2016-2018年,在矿床东北部,向彼得罗夫斯基向斜褶皱东翼方向进行了矿内勘探。对以往研究的分析。彼得罗夫斯基含铁石英岩矿床位于右岸磁异常区的西南偏远地区。矿床的地质构造划分为两组岩石:前寒武纪基底的结晶岩和位于其上的松散新生代沉积物。前寒武纪的岩石是高度变质和错位的结晶基岩,以太古宙和下元古代地层为代表。下元古代地层以ingol - ingulets系列为代表,由(自下而上)划分为:zelenorichenska、artemivska、radionivska套。Artemivska套房在被调查的领土上是生产性的。构造平面上,Petrovskiy矿床为挤压向斜褶皱,西翼呈锥形,东翼向北伸展。在这方面,研究的对象是东翼。研究的目的和任务。研究的主要目的是确定含铁石英岩的矿物学变异性,根据其化学成分分配矿石的矿物学品种,并确定这些品种在东翼生产地层内扩展的规律。通过对岩石资料进行化学分析,计算磁性模量MM和氧化模量MO,并在铁的磁化-氧化(MM-MO)坐标下建立图解,解决了这些问题。介绍文章的主要材料。在Petrovsky向斜褶皱东翼,鉴定出8个矿物学品种:硅酸盐-磁铁矿石英岩、硅酸盐-磁铁矿石英岩、磁铁矿-硅酸盐石英岩、磁铁矿-磁铁矿石英岩、磁铁矿-赤铁矿石英岩、磁铁矿-赤铁矿石英岩、赤铁矿-赤铁矿石英岩。在工作区的边界上,确立了由中心含磁铁矿的赤铁矿石英岩向外围含磁铁矿的硅酸盐石英岩的规律变化。在同一方向上,改变费托内容的规律。, Femagn。硫(S)。然而,在含铁石英岩的基础上,由于形成了榴辉岩体和反射率交代岩体所引起的交代作用叠加,打乱了矿床向斜构造东翼生产层的自生矿物学地带性。

Study of mineralogical variability of ferruginous quartzites of productive strata of the eastern wing of the Petrovsky synclinal fold with using diagram Mm-Mo
Relevance of the problem. Petrovsky deposit is promising area for the extraction of magnetite ores. Detailed research on this deposit was carried out in the 80 years of the last century, but with the deepening and expansion of the pit data from previous studies have lost their relevance. In 2016-2018 years, in the north-eastern part of the deposit, an in-mine exploration in the direction of the eastern wing of the Petrovsky synclinal fold was carried out.Analysis of previous research. Petrovsky deposit of ferruginous quartzites is located in the remote southwestern part of the area of the Right Bank magnetic anomalies. Two groups of rocks were defined in the geological structure of the deposit: the crystalline rocks of the Precambrian base and the loose Cenozoic deposits that were on the top of them. Rocks of the Precambrian Age are highly metamorphosed and dislocated ones of the crystalline base and are represented by Archean and Lower Proterozoic formations. Lower Proterozoic formations are represented by the Ingul-Ingulets series which is divided by the (bottom up): zelenorichenska, artemivska, radionivska suites. The Artemivska suite is productive in the territory under investigation.In the structural plan, the Petrovskiy deposit is a compressed synclinal fold, the western wing of which is taper out, and the eastern wing extends in the northern direction. In connection with this, the object of research was the eastern wing.Purpose and tasks of research. The main purpose of the study was identification of the mineralogical variability of ferruginous quartzites, the allocation of mineralogical varieties of ores according to their chemical composition and to determine the regularities of expanding of these varieties within the productive strata of the eastern wing. These tasks were resolved using chemical analysis of rocks data, calculation of magnetic module MM and oxidation module MO, and the construction of a diagram in the coordinates of magnetization-oxidation of iron (MM-MO).Presentation of the main material of the article. Within the eastern wing of the Petrovsky synclinal fold, the eight mineralogical varieties of the ore were identified: silicate quartzites with magnetite, silicate-magnetite quartzites, magnetite-silicate quartzites, magnetite quartzites with hematite, hematite-magnetite quartzites, magnetite-hematite quartzites, hematite quartzites with magnetite. In the boundaries of the work area of a regular change of varieties of ores from hematite quartzites with magnetite in the central parts to silicate quartzites with magnetite on the periphery was established. In the same direction the regularities of changing the content of Fetot., Femagn. and sulfur (S) were elaborated. However, the authigenic-mineralogical zonality of the productive strata of the eastern wing of the syncline structure of the deposit was disturbed as a result of the overprint of metasomatic processes caused by the formation of bodies of aegirine and rebekitic metasomatites on the basis of ferruginous quartzites was established.
