...D. N. Ravat; L. W. Braile; W. J. Hinze Abstract A three-dimensional gravity and magnetic model of the Bloomfield Pluton near New Madrid, Missouri, has been generated that provides an excellent match to the observed gravity and magnetic anomaly maps. Although this modeling is inherently non-unique...

... Abstract Geotectonic, isotopic, and mineral-zoning studies indicate that southerly derived Mississippi Valley-type (MVT) ore fluids were channeled out of the Reelfoot Rift into southeast Missouri by the Bloomfield Lineament Zone (BLZ). This is consistent with the hypothesis that at least some...

... and elliptical plutons, and is associated with a silicified carbonatite complex. The combined length of the province is nearly 80 km and it outcrops over an area of 440 km 2 . The plutonic rock types range from foyaite to aegirine granite but each individual pluton may be classified as either over- or under...

... to Cretaceous. The major intrusions in the New Madrid seismic zone are the Bloomfield and Covington plutons and Osceola Igneous Complex (OIC). Based on available drillhole data very close to these plutons, Hildenbrand et al. ( 2001 ) inferred the Bloomfield and Covington plutons to be of pre-Ordovician...

... and also subparallel to the borders of the plutons and to the foliation in the wallrock. Kinematic indicators in both granite and wallrock reveal sinistral movement in the Ubendian-belt shear zones and top-to-the-ESE thrusting in the Irumide-belt shear zones. The overall parallelism of magmatic...

... Argentina, and a crystalline basement suite of metamorphic rocks (18%) and magmatic (mainly plutonic) rocks (20%). Due to the absence of typical lithologies, the Brazilian Shield, the Paraguay belt, and the southern Arequipa-Antofalla block could be excluded as possible source areas. The crystalline...
