Примеры seam

• The thinner seams also have a noticeable component of sphenophyll spores, indicating significant areas of open conditions allowing colonization by these scrambling plants.

• The coal seams above p3 are not correlatable across the basin.

• Note that the rock displays only one fabric: a matrix foliation of mostly thin mica seams and elongate quartz grains.

• Clastic layers up to 10 cm thick are common within thick seams.

• In thin-sections, the gneisses are cut by narrow pressure solution seams and narrow cataclastic shear zones.

• The surfaces which appear as dark seams in hand specimen are stylolitic in mor phology and vary in width from 0.01 to 0.2 mm.

• Only then will the limitations, error traps, and therapeutic seams surface, be recognized, and demand remediation.

• Alteration of silicate phases is common adjacent to the chromitite layers and seams.
