Influence of solar gravitational field stress on iron ore distribution
太阳引力场应力对铁矿石分布的影响

摘要

铁矿石储量关于纬度的分布，两个峰值纬度坐标47.5°和－22.5°，太阳引力场应力在经度线切线上投影的平均值，两个极大值纬度坐标±45°，二者对比的结果是北半球47.5°与45°基本一致，南半球－22.5°与－45°相差较大（利用非洲板块向北的漂移速度0.01m/年，以及铁矿石大量产生于约5亿年的寒武纪，能够说明二者在寒武纪时期，峰值纬度坐标在－45°上也基本一致）。物理机制：熔岩中质量密度较大的物质总是沿应力梯度正方向迁移，由此，质量密度大于熔岩的铁矿石沿经度线向±45°纬度线聚集，同时沿径向下沉。海岭上可能存在铁矿石

Abstract

The distribution of iron ore reserves with respect to Latitude,the Latitude coordinates of the two peak values are 47.5°and－22.5° the average value of the stress of the solar gravitational field projected on the tangent of the Longitude line,and the two peak Latitude coordinates 45°,the comparison results show that 47.5° and 45°in the northern hemisphere are basically the same,while －22.5° and －45° in the southern hemisphere are quite different (using the northward drift speed of the African plate of 0.01 m/year, and the fact that a large amount of iron ore was produced in Cambrian of about 500 million years,it can be shown that the peak latitude coordinates of the two were basically the same at －45° during Cambrian). physical mechanism:The material with higher mass density in Lava always migrates along the positive direction of stress gradient,so the iron ore with higher mass density than lava gathers along the Longitude Line to the Latitude line of 45°,and sinks along the radial direction .There may be iron ore on the ridge.
