Add a definition These correlations between composition and volcaniclithicfragmenttype are approximate, at best. From Wikipedia ![]() Lithic fragments are commonly embedded in the larger pumices. From theCambridge English Corpus In general, these sandstones are poorly sorted matrix-supported quartz wackes with framework grains of detrital quartz, lithic fragments, feldspar and pyroxene. From theCambridge English Corpus Lithic sandstones can have a speckled (salt and pepper) or gray color, and are usually associated with one specific type oflithicfragment(i.e., igneous, sedimentary, or metamorphic). From Wikipedia ![]() The few lithic fragments within the deposit represent either xenoliths or reworked mudrock. From theCambridge English Corpus At the base is a thin, fine-grained, stratified pumice bed 10 cm thick, with abundant small pebbly lithic fragments (10-30 %), which probably reflect an initial vent-clearing episode. From theCambridge English Corpus In this case there would have been some sediment that was completely disaggregated into the magma, appearing as individual quartz grains or lithic fragments within the tuffs. From theCambridge English Corpus It is composed of oolites and lithic fragments. From Wikipedia ![]() Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when lithified) and pumice lapilli, commonly with scattered lithic fragments. From Wikipedia ![]() Detrital particles can consist of lithic fragments (particles of recognisable rock), or of monomineralic fragments (mineral grains). From Wikipedia ![]() This tectonic setting provides the source of the lithic fragments, either through arc volcanism, thin-skinned faulting, continental collisions, unroofing, and subduction roll-back. From Wikipedia ![]() Greywacke sandstones are a heterogeneous mixture of lithic fragments and angular grains of quartz and feldspar, and/or grains surrounded by a fine-grained clay matrix. From Wikipedia ![]() The dunes were created by and are replenished by granitic deposits, specifically quartz, feldspar, lithic fragments, and amphibole. From Wikipedia ![]() The compaction is usually more effective on the (typically) weaker lithic fragments in comparison to the stronger, coarser-grained framework grains. From Wikipedia ![]() In contrast, most high-silica ash (e.g. rhyolite) consists of pulverised products of pumice (vitric shards), individual phenocrysts (crystal fraction) and some lithic fragments (xenoliths). From Wikipedia ![]() The deposit is well sorted with density and size of pumice, and the content and size of the lithic fragments increasing upwards. From Wikipedia ![]() Although it is composed primarily of quartz grains, feldspathic and lithic fragments are present in significant quantities, as are a variety of bioclasts derived from marine invertebrates. From Wikipedia ![]() Vitric ash particles from high-viscosity magma eruptions are typically angular, vesicular pumiceous fragments or thin vesicle-wall fragments while lithic fragments in volcanic ash are typically equant, or angular to subrounded. From Wikipedia ![]() These examples are from corpora and from sources on the web.
