Eocene-Oligocene planktonic foraminifera of ODP Hole 135-841B
A middle Eocene to lower Oligocene sedimentary sequence was drilled at Site 841 in the Tonga forearc region during Ocean Drilling Program Leg 135. A 56-m-thick sequence of... -
Geochemistry of felsic rocks and minerals of ODP Hole 135-841B
A felsic volcanic series (605-825 mbsf) overlain by upper Eocene shallow-water sediments (500-605 mbsf) and basalticandesitic sills that intruded into sediments of Holocene to... -
Geochemistry of ODP Hole 135-839B basalts
Experimental phase relations were used to assess the role of volatiles and crustal level fractional crystallization in the petrogenesis of lavas from Hole 839B in the central... -
Geochemistry of ODP Hole 135-839B lavas
Four petrographic lava types occur, ranging from aphyric to moderately phyric clinopyroxene-olivine tholeiitic basalts (Unit 1); olivine-clinopyroxene picritic basalts, sparsely... -
Petrology and geochemistry of sedimentary Unit III of ODP Hole 135-840B
The sedimentary sequence recovered at Site 840, on the Tonga frontal-arc platform, is 597.3 m thick and is subdivided into three lithostratigraphic units. The lowermost, late... -
Thermal diagenesis of clay minerals within volcanogenic material from ODP Sit...
Clay minerals are examined in detail in the sediment from the Tonga Trench margin at Site 841 (Leg 135 ODP). The changes in amount and nature of secondary clays with depth... -
Geochemistry of the oceanic crust from ocean drilling samples
This book presents new data on chemical and mineral compositions and on density of altered and fresh igneous rocks from key DSDP and ODP holes drilled on the following main... -
Chemical and boron isotopic compositions of volcanics from ODP Sites 135-834 ...
The influence of fluid flux on petrogenesis in the Tonga-Kermadec Arc was investigated using ion microprobe measurements of B/Be and boron isotope ratios (11B/10B) to document... -
Chemical and strontium isotopic compositions of interstitial waters from sedi...
The depth variations in the major chemical components dissolved in interstitial waters from the Tonga margin (ODP Site 841) are much more pronounced than those usually observed... -
Isotopic composition of rocks from the Lau/Tonga back-arc basin, data of DSDP...
New trace element, Sr-, Nd-, Pb- and Hf isotope data provide insights into the evolution of the Tonga-Lau Basin subduction system. The involvement of two separate mantle... -
Composition, oxygen isotope and crystallisation temperature of clay samples f...
Oxygen isotopic compositions of clay minerals were determined on representative samples of the volcano-sedimentary series from Site 841 ODP (Tonga forearc). This isotopic study... -
