(1) The metal content of the fluids thus reflects the trace-element composition of the subjacent source rocks which, in mid-ocean ridges, are basaltic.(2) The cause of crater formation can be envisaged as the subsidence of a structurally bound Triassic layer into a subjacent Zechstein succession, which was extending and thinning.(3) Viral antigen extended, in a time-dependent fashion, from nasal epithelium into the subjacent lamina propria and along olfactory nerves in cells interpreted to be perineural fibroblasts.(4) Recent studies proposed that the Cretan detachment is a shallowly north-dipping normal fault, which formed subparallel to the subjacent subduction thrust in the Early Miocene.(5) At 187 m, a thin bed of iron-stained quartz sandstone drapes across an irregular surface cut into oolitic dolomitic grainstones that represent the latest phase of the subjacent shallowing record.(6) Further evidence in favour of the variable analysis comes from the fact that the distribution of null objects is sensitive to subjacency .(7) In this paper, we take a similar approach to one of the classic linguistic universals: subjacency .
