Many microtektites were collected from sediment samples at depths of 386.17-386.27 mcd. They are mostly spherical and oval in shape, but also include teardrops, saddles, buns, dumbbells, disk shapes and fragments. The major elements of these microtektites were measured by microprobe. Based on Harker plots and Niggli parameters of the major elements, our conclusion is that microtektites from ODP Site 1144 came from Australian normal microtektites. The parent materials are complicated in composition, and may include some clastic sediment which has not yet been chemically altered. Another one or two components involved were probably derived from clay and sandstone.completedPetrology of meteorites and tektitesSedimentary petrologyGeochemistry of rocks, soils, and sedimentsAustralasiaAustraliachemical compositionclastic rocksclastic sedimentsclaygeochemistryLeg 184major elementsmicrotektitesNorth PacificNorthwest PacificOcean Drilling ProgramODP Site 1144Pacific Oceanparent materialsphysicochemical propertiessandstonesedimentary rockssedimentsSouth China SeatektitesWest Pacificurn:org.iodp:exp:184urnlargerWorkCitationcampaignurn:org.iodp:exp:184:site:1144urnlargerWorkCitationstudyurn:org.iodp:exp:184urnlargerWorkCitationcampaignChinesegeoscientificInformation117.2508117.250820.031120.0311
