...ROBERT M HUTCHINSON AbstractEnchanted Rock batholith is one of several moderate-sized plutons that intruded a framework of tightly folded Precambrian metamorphic rocks in Middle Precambrian time. Tectonic features within the mass and structural attitude of wall rocks indicate the northern third...

... to anorthositic rocks, a separate mangeritic series of primarily intermediate composition, and granite of definite rapakivi affinity comprise an anorogenic “trinity” of world-wide occurrence. With the exception of the 1.76 b.y. Montello batholith (Wisconsin), this episode in North America is restricted...

... and minor monzogranite that dominates the batholith. The potassic series also includes fine- to medium-grained biotite granite found in numerous, small, late-stage plutons throughout the batholith. The sodic series is found in seven plutons comprised of a wide range of rock types (∼44–78 wt % SiO2...

... the metasomatizing fluid was relatively poor in Rb (seawater derived brines) or richer in Rb as in many hydrothermal waters. Diagenetic fluids may originate from seawater, or meteoric water enriched in cations by water–rock interactions along their subsurface migration paths and/or by dissolution of evaporites...
