Granulometric analysis of aeolian dust deposits with Malvern Morphologi G3-ID

Automated imaging provides a unique technique to gather direct information on granulometric characteristics of sedimentary particles. Granulometric data obtained from automatic image analysis of Malvern Morphologi G3-ID is a previously does not applied, brand new technique for particle size and shape analyses in sedimentary geology. Size and shape data of several hundred-thousand individual particles were automatically recorded for each sample from the captured high-resolution images. Several size (e.g. circle-equivalent diameter, major axis, length, width, area) and shape parameters (e.g. elongation, circularity, convexity) were calculated by the instrument software. While the mean light intensity after transmission through each particle is automatically collected by the system as a proxy of optical properties of the material.

  1. I heard that Car should be washed even after the rain as well because of the dust around the air. Thats why I do car wash at victoria park.
