“…The linear relationship of (La/Ta) n vs. (Th/Ta) n indicates the mixing between mantle melts and upper continental crust ( Fig. 10a; Ingle et al, 2002). The quantitative modeling suggests that they may origin from E-MORB source and have experienced a minor crustal assimilation (< 4%; Fig.…”

“…Normalized lithophile element patterns of the tholeiites reflect the presence of weakly enriched source and enriched one with pronounced Zr and Hf negative anomaly for a part of samples as well (Fig. 7c) which mantle enrichment processes supposed to be connected with metasomatic acting of lamprophyric melts (Ingle et al, 2002). The correlation analysis of lithophile element contents in the basites of the Schirmacher Oasis (as an example, element-Th correlation diagrams are shown in Fig.…”

“…The eastward propagation of plume magmatism in Antarctica along the ancient collision zone reflects the processes that occurred in the apical part of the plume at about 180-110 Ma. The established geochemical similarity between the basalts of the continental margin of eastern India (Rajmahal traps) and Southwestern Australia (Bunbury basalts) and the tholeiites of the Kerguelen Plateau implies the assimilation of the ancient continental crust of Gondwanaland by the basaltic melts (Ingle et al, 2002 Sr = 0.70568,143 Nd/ 144 Nd = 0.512629 (Fig. 12).…”

“…The layered basement of the Bruce Bank is a pile of volcanic rocks, up to 3.5 km thick, underlain by the thinned continental crust (Leitchenkov & Guseva, 2006). The results of deep-sea drilling in the Elan Bank in the western spur of the Kerguelen Plateau also suggest its continental origin (Ingle et al, 2002). Thus, the complex formation of an ancient spreading zone during the initial stages of ocean opening resulted in the detachment of continental lithospheric blocks of different size, which could significantly affect the geochemical character of tholeiitic magmatism within rift zones.…”

The Kerguelen Plateau and Broken Ridge form a large igneous province (LIP) in the southern Indian Ocean. The main objectives of Ocean Drilling Program Leg 183 were to understand the origin and evolution of this LIP and the impact of its formation on the environment. Igneous basement (33 to 233 m of penetration) has been recovered from 11 drill sites on the LIP, and 7 are Leg 183 sites. Studies of the basement and sediment cores lead to the following conclusions. Although an important caveat is that we have access only to uppermost basement of a thick (~20 km) igneous crust, these results are inconsistent with massive volcanism associated with a single plume head and continental breakup. 2. The uppermost igneous basement is dominantly tholeiitic basalt. Based on the physical characteristics of the lava flows, which indicate subaerial eruption, and the occurrence of overlying terrestrially derived sediments containing wood fragments, fern remains, and terrestrial palynoflora, much of the LIP was above sea level when magmatic output was high. 3. The geochemical characteristics of basalt forming the LIP are unlike mid-ocean-ridge basalt (MORB). There are, however,
