VOLUME AND PROPERTIES OF BURIED ROCKS CONTAINING IMPACT MELT IN THE ZHAMANSHIN METEORITE CRATER: ASSESSMENT FROM THE ANOMALOUS MAGNETIC FIELD

Abstract

The Zhamanshin meteorite impact crater (Kazakhstan, 48°37' N, 61°94' E, diameter 5.5–13.0 km, age 0.8–1.0 million years) continues to attract the attention of researchers. Craters formed as a result of an asteroid impact on the Earth’s surface are characterized by the presence of a magnetic field anomaly. The results of numerical modeling of the magnetic anomaly of the Zhamanshin crater are presented based on the ideas about the volume and magnetic properties of rocks containing solidified impact melt buried inside the crater. The obtained results correspond to the general picture of the magnetic anomaly of the crater under study.
