  • Insoluble particle concentration in ice cores is commonly analyzed as a proxy for variations in atmospheric mineral dust (aerosol concentration). However, recent studies have revealed that the mineral dust is not only a constituent of the particles but that biogenic organic particles are also contained. We microscopically analyzed insoluble particles in a shallow ice core drilled on a mountain glacier, the ürümqi Glacier No. 1, in eastern Tienshan, China. We distinguished different morphologi-cal particles in the ice core and quantified them separately. Results showed that the insoluble particles in this ice core consisted mainly of mineral particles, amorphous organic particles, pollen, and micro-organisms...

Abstract: Insoluble particle concentration in ice cores is commonly analyzed as a proxy for variations in atmospheric mineral dust (aerosol concentration). However, recent studies have revealed that the mineral dust is not only a constituent of the particles but that biogenic organic particles are also contained. We microscopically analyzed insoluble particles in a shallow ice core drilled on a mountain glacier, the ürümqi Glacier No. 1, in eastern Tienshan, China. We distinguished different morphologi-cal particles in the ice core and quantified them separately. Results showed that the insoluble particles in this ice core consisted mainly of mineral particles, amorphous organic particles, pollen, and micro-organisms...
