... megascopically to the underlying Lithic Ridge Tuff, but contain much more
quartz and only very rare sphene. At the type locality at Tram Ridge, near
northern Crater Flat, and near the distal edges of the member (fig. 11), lithic
fragments are ...

Here and there a small but well-formed crystal of garnet, bundles of tabular
prehnite crystals, and minute but brilliant faces of epidote crystals are
distinguishable megascopically. The metallic minerals occur similarly as small
individuals and as ...

The quartz-bearing latite is practically indistinguishable either megascopically or
microscopically from the normal latite except for the sporadic quartz crystals.
These are very small, and in some slides not more than two or three rounded
grains, ...

Several general terms have been applied to porphyrice to denote the crystallinity
of the groundmass: VITROPHYRE, a porphyry with megascopically glassy
groundmass. The texture may be called vrrnornrnrc or vr'rsom-rrc. Feasoruvas ...

However, regardless of dolomitization processes, oxygen isotope compositions
of megascopically unaltered Eldorado Dolomite and Prospect Mountain Quartzite
(DDH 728; fig. 2A, table 8) have a limited range of a few per mil. Average 5180 ...

Megascopically it closely resembles nonporphyritic facies of the quartz
monzonite, although slight differences are generally recognizable (fig. 21H). The
most obvious features of the alaskite that distinguish it from the quartz monzonite
are a ...

Biotite in small flakes is present in small amount, and many yellowish brown
crystals of titanite are rather noticeable megascopically. A little muscovite is
present, but it is quite inconspicuous. The most interesting feature of the rock is
the potash ...

... the information which can be derived from tephras requires extension of
landbased studies in the marine realm, where, within about 1000 km of the
source, tephras may be found as clear and discrete megascopically
distinguishable layers.
