Radioisotopes in the Diabase Sill (Upper Precambrian) at

 · The diabase sills and dikes are believed to be the intrusive equivalents of the Cardenas lava flows but they are not found in direct association with the Cardenas Basalt.11 12 13 Thus the relationship between them is obscure because the direct feeders to the flows have never been recognized among the available diabase outcrops. The diabase sills are in fact confined to the lower

Determining the origin of volcanic rocks in the mélange

 · An ENE‐WSW‐trending localized basalt‐diabase outcrop along the SE margin of Luk Ulo Mélange Complex has been suggested as intrusive rocks cut through the Paleogene Totogan and Karangsambung formations. However the absolute dating of the volcanics is older than the inferred relative age of the sedimentary formations hence the in‐situ

Chondrite-normalized REE patterns show that the magnetite separates from disseminated banded and massive iron ores which are distinct from those in magmatic Fe-Ti deposits.
