Exempel på hur man kan använda THOLEIITES i en mening

• During the Upper Triassic evaporites continued being precipitated, crowned by ophitic lava flows (dolerites and tholeiites).
• Rocks sampled from the Hollister Ridge have yielded basalts, alkali basalts, hawaiites, picrites and tholeiites as well as granites, which are most likely dropstones transported to the ridge by icebergs.
• Among the rocks found at Ita Mai Tai are alkali basalts, basalts, clays, hawaiites, limestone, muds, picrites, tholeiites, trachytes and trachybasalt; volcanic rocks contain potassium feldspar and plagioclase.
• The volcanic rocks include alkali basalts, basanite, hyaloclastite, palagonite, picrite, pumices, basaltic tuffs, trachybasalt and trachyte and define an alkaline ocean island basalt suite although the existence of tholeiites as in Hawaii is possible and substantial amounts of evolved volcanic rocks have been recovered; these were probably generated by basaltic melts in magma chambers.
