detritaalisiin
Detritaalisiin is a Finnish term used in geology and sedimentology to refer to detrital or clastic materials and processes. It denotes sediments and sedimentary rocks that are composed primarily of mechanically produced fragments derived from weathering and erosion, as opposed to minerals that originate by chemical precipitation or biological activity.
Detrital materials typically include quartz and feldspar grains, lithic fragments, and clay minerals. They are commonly
Analyses of detritaalisiin contexts often involve grain-size distribution, modal mineralogy, and detrital geochronology (for example detrital
Within broader studies, detritaalisiin processes also cover weathering, transport, sorting, and diagenetic changes that affect grain
