Simanovich Igor M 1979 (Table 2) Chemical composition of potassium feldspars from DSDP Hole 19-192A dataset Geological Institute, Russian Academy of Sciences, Moscow https://doi.org/10.1594/PANGAEA.776048 Simanovich Igor M 1979 Potassium feldspar in oceanic basalts other Litologiya i Poleznyye Iskopaemyye (Lithology and Mineral Resources) 14(1) 52-61 Secondary potassium feldspar (K-feldspar) in oceanic basalts represented by low-temperature sanidine with low content of albite molecule. K-feldspar replaces nucleus of phenocrysts and large microlites of plagioclase. Occurrence of K-feldspar increases with age of rocks; in Pliocene and Pleistocene basalts from zones of mid-ocean ridges K-feldspar is absent. K-feldspar is developed in basalts of various geological, textural and structural types. Correlation of K-feldspar occurrence with primary alkalinity of basalts is absent. High (1-6%) contents of K2O in basalts in almost all cases are associated with development of K-feldspars in them. In basalts containing K-feldspars, a clear correlation between K2O and H2O (R = 0.55) is observed. 164.7135 164.7135 53.0095 53.0095 164.7135 53.0095 1971-08-30T00:00:00 1971-08-30T00:00:00 1043.75 1056.75 vertical profile ARCOD Archive of Ocean Data Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven AWI https://www.awi.de/ https://ror.org/032e6b942 DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 19-192A 53.0095 164.7135 North Pacific/GUYOT -3014.0 1971-08-30T00:00:00 Leg19 Leg19 1971-07-24T00:00:00 1971-07-24 1971-09-08T00:00:00 1971-09-08 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Creager, Joe S Creager, Joe S Scholl, David W Scholl, David W doi:10.2973/dsdp.proc.19.1973 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 1057 m 37.7 m 6 cores; 47 m cored; 0 m drilled; 80.2 % recovery 27 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Simanovich Igor M Sample label DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Depth sed [m] Depth, top/min Depth top m depth http://purl.obolibrary.org/obo/PATO_0001595 Length L http://dbpedia.org/resource/Length Simanovich Igor M Depth top [m] Depth, bottom/max Depth bot m depth http://purl.obolibrary.org/obo/PATO_0001595 maximal max Length L http://dbpedia.org/resource/Length Simanovich Igor M Depth bot [m] Silicon dioxide SiO2 % https://en.wikipedia.org/wiki/Silicon_dioxide silicon dioxide http://purl.obolibrary.org/obo/CHEBI_30563 Dimensionless Ratio ψ Microprobe Simanovich Igor M SiO2 [%] Aluminium oxide Al2O3 % aluminium oxide http://purl.obolibrary.org/obo/CHEBI_30187 Dimensionless Ratio ψ Microprobe Simanovich Igor M Al2O3 [%] Calcium oxide CaO % https://en.wikipedia.org/wiki/Calcium_oxide calcium oxide http://purl.obolibrary.org/obo/CHEBI_31344 Dimensionless Ratio ψ Microprobe Simanovich Igor M CaO [%] Sodium oxide Na2O % sodium oxide Na2O https://pubchem.ncbi.nlm.nih.gov/compound/73971 Dimensionless Ratio ψ Microprobe Simanovich Igor M Na2O [%] Potassium oxide K2O % potassium oxide http://purl.obolibrary.org/obo/CHEBI_88321 Dimensionless Ratio ψ Microprobe Simanovich Igor M K2O [%] Sum Sum % sum http://www.oxforddictionaries.com/definition/american_english/sum Dimensionless Ratio ψ Calculated Simanovich Igor M Sum [%] supplement citable author39715 basis12 campaign141 campaign3374865 event12263 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 inst32 inst41 license101 method10974 method50 method5059 method6499 param1825 param3 param4 param6166 param702 param704 param708 param790 param811 pi39715 project4 project4026 ref35077 sourceinst1192 term1073131 term1073224 term1074034 term1074050 term20726 term2632269 term38263 term38380 term38561 term41056 term43794 term43863 term49257 topotype3
