Centimeter- To Meter-Scale Structural and Petrographic Variations in a 3-D Exposure in the Migmatite Granite Complex, Southern Maine

Migmatites are a meta-igneous rock which crystallized early in the stages of melt, capturing the process of anatexas, or partial melting. As part of a multi-disciplinary study of rocks in the Migmatite-Granite belt of the Northern Appalachians, we have documented variations at the cm- to m- scale of fabrics and geometry of granitic bodies in a large, 3-D exposure in W. Cumberland, ME. This exposure is new as the homeowners have removed glacial till from the property, re-exposing glacially polished 76m x 24m pavement adjacent to a 15m high cliff face. An exposure of this magnitude and detail is rare since it is in an area of low outcrop density. This provided a unique opportunity to study a large 3-D outcrop within the Migmatite-Granite Complex (MGC). The outcrop is dominated by metasedimentary metatexite migmatite which includes two 3-m-wide concordant amphibolite layers. The fabric of the outcrop exhibits a NE-SW trend with moderate SE dips. This outcrop resembles the same fabric found in regional data, which was expected. Dextral shear is indicated by asymmetric trails around porphyroblasts, boudinage, and ptygmatic folds of stromatic migmatite. The fabric indicating the shear is found within leucosomes, granitic bodies within the migmatite, indicating younger deformation than migmatite formation; this is also consistent with regional MGC data. Migmatite layers are intruded by granitic rocks with grain sizes from coarse to pegmatitic. Observations of contacts indicate cm-scale bake zones, also indicating the granite intruded following the formation of migmatite. Granite bodies are generally cm- to m- thick 2-mica coarse-grained granite to pegmatite. Cm-scale, medium grained granitic dikes are located throughout the outcrup cutting all structures, consistent with other rocks found throughout the MGC

Differential effects of methyl jasmonate on growth and division of etiolated zucchini cotyledons

Measurements of the jet energy calibration and transverse momentum resolution in CMS are presented, performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of 7TeV, corresponding to an integrated luminosity of 36pb-1. The transverse momentum balance in dijet and γ/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transverse momentum resolution. The results are presented for three different methods to reconstruct jets: a calorimeter-based approach, the "Jet-Plus-Track" approach, which improves the measurement of calorimeter jets by exploiting the associated tracks, and the "Particle Flow" approach, which attempts to reconstruct individually each particle in the event, prior to the jet clustering, based on information from all relevant subdetectors
