The behavior of heavy minerals in lithostream

Abstract

This study is concerned with the eolian deposits on the Baikal shore. It has been established that (1) the eolian sands are distinctly divided into two sequences: Khuzhir (Late Pleistocene) and Peschanka (Holocene); (2) the ilmenite enrichment of the sands is due to the removal of sand grains (containing mainly light minerals) by strong winds up the shore, first, from a dewatered beach zone, and then, from zones of psammitic-material transition. This leads to the concentration of ilmenite and other heavy minerals, first, within the beach zone, and then, within the zones of prevailing eolian-sand transition. The accumulation-transition zones are most enriched in heavy minerals, including ilmenite; (3) the ilmenite content in the study Ti-ore placer deposit shows a high correlation (R = 0.89) with the total content of heavy minerals.

Atmospheric Processes in the South Baikal Basin and Their Role in Relief Formation

“…For instance, the volume of modern aeolian deposits on the coast of Nyurganskaya Guba, as calculated by B.P. Agafonov, reaches 3 million m 3 [23].…”

Fundamental Problems of the Electrodynamics of Heterogeneous Media with Boundary Conditions Corresponding to the Total-Current Continuity

“…An analysis of these figures shows that at the places of discontinuity, on the wedges, force lines of the electromagnetic field concentrate. According to (Akulov, N. S., 1939), precisely wedges are often the sources and sinks of the vacancies that determine, for example, the hardness and plasticity of a solid body. Also, we modeled the propagation of waves in media, when domains possess magnetic properties.…”

“…According to (Shul'man, Z. P. & Kordonskii ,V. I., 1982), the size of domains is as follows: 0.05 m in iron, 1.5 m in barium ferrite; 8 m in the MnBi compound, and 0.5-1 m in the acicular gamma ferric oxide. According to (Akulov, 1961), the size of a domain may reach 10 -6 cm 3 (obtained by the method of magnetic metallography). As a rule, an abrasive exhibits a distinct shape anisotropy, whereas the frequency of the effect is determined by the concentration of abrasive particles in a hydrophobic solution and by the velocity of its motion.…”
