MECHANICAL STRENGTH AND FLOW PROPERTIES OF ICE-SILICATE MIXTURE DEPENDING ON THE SILICATE CONTENTS AND THE SILICATE PARTICLE SIZES

摘要

Icy satellites have an icy crust and mantle and are composed of mixtures of ice and silicates. Stripe patterns showing layered structures with different sand contents have been discovered on the polar cap on Mars. There could be a wide range of temperature conditions from the melting point of ice to below 100 K in icy satellites and on Mars. Therefore, it is important to study the Theological properties of ice-silicate mixtures at wide temperatures to elucidate the tectonics of icy satellites and the flow dynamics of ice sheets on Mars.
