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.
