Lithostratigraphy and petrology of Lachman Crags and Cape Lachman lava-fed deltas, Ulu Peninsula, James Ross Island, north-eastern Antarctic Peninsula: Preliminary results

Abstract: This paper presents the preliminary results regarding the lithostratigraphy, petrography and petrology of James Ross Island Volcanic Group dominating the Lachman Crags and Cape Lachman lava-fed deltas in the Ulu Peninsula, James Ross Island north-eastern Antarctic Peninsula. Studied lava-fed deltas were produced via Late Miocene to Pleistocene sub-marine and sub-glacial volcanism and made up four main lithofacies: a- bottomset pillow lavas, peperites and associated volcanoclastic/siliciclastic deposits; b- for… Show more

“…() and Altunkaynak e t al . () show the K/Ca ratio being in the range 0.063–0.485, coinciding with our XRF‐based K/Ca ratio of JRIVG basalts (0.040–0.355) and hyaloclastites (0.088–0.424). This is similar to the values calculated for aeolian deposition on the studied glaciers (0.463–0.639), but the samples from individual glaciers differ in Fe/Ti ratio, as can be seen in Figure .…”

“…The results were validated by the analysis of certified reference material CH‐4 (Natural Resources Canada), because of the similar proportions of the main elements and most of the trace elements analysed both in the snow samples as well as in the background geological samples (volcanic and sedimentary rocks). The comparison of XRF‐based trace element proportions and elemental ratios with ICP‐based geochemical data from James Ross Island Volcanic Group (JRIVG) basaltic rocks (Košler et al, ; Altunkaynak et al, ) proved the suitability of the XRF spectrophotometry for our study. Replicate measurements of the same sample showed differences of <1% for all assessed elements.…”
