(eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office) 90 https://doi.org/10.2973/dsdp.proc.90.125.1986 1145-1159 Pale green laminae < 2 mm thick are common features of the Neogene and Quaternary sediment of Lord Howe Rise. We believe these laminae represent diagenetically altered volcanic ash layers from regional volcanic events. Although no consistent high abundances of volcanic glass are found within the laminae, the volcanic origin of the laminae is suggested by (1) similar temporal distribution of the laminae and the distribution of volcanic ash layers elsewhere in the southwest Pacific; (2) the high abundances of authigenic smectite in the laminae; and (3) the common occurrence of iron sulfides in proximity to most of the laminae. The resulting tephrostratigraphy is considerably more complex and detailed than was previously known. 164.4487 164.4487 -31.5843 -31.5843 164.4487 -31.5843 1982-12-19T00:00:00 1982-12-19T00:00:00 22.06 182.9 DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 90-591 -31.5843 164.4487 South Pacific/Tasman Sea/CONT RISE -2131.0 1982-12-19T00:00:00 Leg90 Leg90 1982-12-02T00:00:00 1982-12-02 1983-01-08T00:00:00 1983-01-08 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html von der Borch, Christopher C von der Borch, Christopher C Kennett, James P Kennett, James P doi:10.2973/dsdp.proc.90.1986 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 283.1 m 276.7 m 31 cores; 283.1 m cored; 0 m drilled; 97.7 % recovery 90-591A -31.5843 164.4487 South Pacific/Tasman Sea/CONT RISE -2131.0 1982-12-19T00:00:00 Leg90 Leg90 1982-12-02T00:00:00 1982-12-02 1983-01-08T00:00:00 1983-01-08 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html von der Borch, Christopher C von der Borch, Christopher C Kennett, James P Kennett, James P doi:10.2973/dsdp.proc.90.1986 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 284.6 m 236.4 m 28 cores; 265.6 m cored; 19 m drilled; 89 % recovery 217 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Event label Event Event Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Gardner James V jim@octopus.wr.usgs.gov Sample label Color description Color desc Visual description Gardner James V jim@octopus.wr.usgs.gov Color desc 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 mbsf Depth sed [m] Epoch Epoch Gardner James V jim@octopus.wr.usgs.gov Epoch Nannofossil zone Nannos zone Gardner James V jim@octopus.wr.usgs.gov Nannos zone Smectite Sme % http://www.mindat.org/min-11116.html Dimensionless Ratio ψ X-ray diffraction (XRD) Optical tools & radiometric sensors X-ray diffractometers http://vocab.nerc.ac.uk/collection/L05/current/LAB26/ Gardner James V jim@octopus.wr.usgs.gov Sme [%] Illite Ill % http://www.mindat.org/min-2011.html illite https://www.mindat.org/min-2011.html Dimensionless Ratio ψ X-ray diffraction (XRD) Optical tools & radiometric sensors X-ray diffractometers http://vocab.nerc.ac.uk/collection/L05/current/LAB26/ Gardner James V jim@octopus.wr.usgs.gov Ill [%] Chlorite+Kaolinite Chl+Kln % Dimensionless Ratio ψ X-ray diffraction (XRD) Optical tools & radiometric sensors X-ray diffractometers http://vocab.nerc.ac.uk/collection/L05/current/LAB26/ Gardner James V jim@octopus.wr.usgs.gov Chl+Kln [%] supplement citable author155 author32220 author866 basis12 campaign212 campaign3374961 event12974 event12975 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 inst41 license101 method10974 method12 method268 method5059 param100493 param14926 param15398 param20544 param295 param296 param790 pi155 project4 ref37410 term1073131 term20737 term2299415 term38263 term40831 term41056 term43794 term43863 term67649
