The Nature and Origin of Cordilleran Magmatism
GEOCHEMISTRY The leucocratic granitic rocks and younger volcanic-plutonic
assemblage are chemically distinct. This is best shown on an AF M diagram (Fig.
7), where the Eocene volcanic-plutonic rocks define a calc-alkalic trend that is ...

The leucocratic monzogranite probably has a total outcrop area of about 5 to 6
km2 and normally is within the more widespread porphyritic monzogranite of
Garnet Mountain. Contacts between leucocratic monzogranite and the porphyritic

In this area, the major rock type is a pink, equi- granular to slightly porphyritic,
generally massive leucocratic granite that has been named (Schmidt, 1976) the
Puritan Quartz Monzonite. The granite intrudes metavolcanic rocks, called the ...

RESULTS AND DlSCUSSlONS Metamorphosed composite intrusive rock The
purpose of this sample was to observe the real 3D texture, particularly to detect
the commingling texture between leucocratic part and melanocratic part.

Cordilleran Metamorphic Core Complexes
Leucocratic Rock. One of the most striking aspects of the gneiss dome is the
abundance of leucocratic rock which increases markedly toward the top where it
is interlayered on all scales with adamellite, amphibolite, and pelitic schist. Figure

A few large sheets of the leucocratic gneiss are present in the Mount Cowen
Gneiss near its northwestern margin; one small stock was also found in addition
to a number of dikes. Three thin sections were studied. The texture of the gneiss
is ...

The eastern side of the K-feldspar-megacrystic- granodiorite-neosome migmatite
(unit 2) is locally invaded by the second minor intrusive component: leucocratic
biotite granodiorite and granite that forms irregular apophyses, as well as ...

deformation include both leucocratic granitoids ranging from alkali feldspar
granite to syenogranite and low-silica charnockite that is likely unrelated to the
contemporaneous leucocratic rocks. Results from U-Pb isotopic analysis of
zircons ...

The magma storage conditions of the distinctive Pu'u Wa'awa'a (PWW) trachyte eruption on HuaHilai Volcano remain poorly understood.
