WhatsApp: +86 18203695377Abstract. Mineral dust particles are thought to be an important type of icenucleating particle (INP) in the mixedphase cloud regime around the globe. While Krich feldspar (Kfeldspar) has been identified as being a particularly important component of mineral dust for ice nucleation, it has been shown that quartz is also relatively icenucleation active. Given quartz typically makes up a ...
