Regional distribution of Heavy-mineral concentrations along the Curonian Spit coast of Lithuania

Heavy-mineral concentrations (HMC) in coastal sands serve as important indicators of hydrometeorological and sedimentological conditions.

Description
Summary:Heavy-mineral concentrations (HMC) in coastal sands serve as important indicators of hydrometeorological and sedimentological conditions. Along the southeast Baltic Sea coast, quartz- and feldspar-rich sands contain variable amounts of heavy minerals, such as garnet, rutile, zircon, magnetite, ilmenite, hornblende, and other accessory minerals. The open sea beach sites range from 25 to 80 m in width and are backed by 5-16 m height foredunes. To examine the patterns in HMC distribution, a total of 303 surface sand samples were collected from the middle of the beach, foredune toe, and stoss slope at 500 m intervals along the entire length of the Lithuanian section. To characterize the relative concentrations of heavy minerals (especially ferrimagnetic), a Bartington MS3 field scanning sensor was used for rapid and effective measurements of low-field volume magnetic susceptibility (MS). Along the Baltic Sea beach, in-situ MS values of Kappa 150 mu SI in surface HMCs.
