The Palaeogene Kangerlussuaq Intrusion (∼50 Ma) of East Greenland displays concentric zonation from quartz-rich nordmarkite (quartz syenite) at the margin, through pulaskite, to foyaite (nepheline in centre; modal layering and igneous lamination are locally developed but there no internal intrusive contacts. This is an apparent violation phase relations Petrogeny's Residua System. We propose that this intrusion layered, grading quartz syenite bottom nepheline top. Mineral whole-rock major...

The Kap Edvard Holm Layered Gabbro Complex is a large layered gabbro intrusion (>300 km2) situated on the opposite side of Kangerdlugssuaq fjord from Skaergaard Intrusion. It was emplaced in continental margin ophiolite setting during early Tertiary rifting North Atlantic. Gabbroic cumulates, covering total stratigraphic thickness >5 km, have typical four-phase tholeiitic cumulus mineralogy: plagioclase, clinopyroxene, ±olivine, and ±Fe–Ti oxides. cryptic variation restricted (plagioclase...

The 160 km2 Caledonian Fongen-Hyllingen complex is an extremely differentiated, layered, basic intrusion, synorogenically emplaced at 5–6 kb in the allochthonous Trondheim nappe complex, situated region of Norway. A zone gabbroic rocks without rythmic layering usually occurs along margin and a supposed feeder to least part preserved. wide variety magmatic sedimentary structures are present c. 10,000 m thick sequence rhythmically layered which vary from olivine-picotite cumulates base...

The Fongen—Hyllingen Intrusion, situated ∽60 km SE of Trondheim, Norway, is a synorogenic layered mafic intrusion Caledonian age 426-2+8⁠. divided into four evolutionary stages based on cryptic variations: Stage I—a basal reversal; II—unchanged mineral chemistry or slight normal evolution; III—a gradual regression; IV— strong fractionation trend Magma replenishment dominated during most the crystallization, i.e. Stages I, II and III Replenishing magma was more dense than resident, evolved...

We present a new methodology to measure the running biomechanics of amputees. This combines use spring-mass model and symmetry index, two standard techniques in literature, but not yet used concert evaluate amputee biomechanics. The was examined context pilot study examine transtibial sprinters showed biomechanically quantifiable changes for small adjustments prosthetic prescription. Vertical ground reaction forces were measured several trials amputees at constant speed. A conjunction with...

Abstract Public humanities happens whenever scholarship interacts with public life. Providing a 10-point typology of humanities, this article explains why we need the – as individuals and societies narrates some moments when have changed world. We discuss rise “public humanities,” critiques field, vision for its future.

Abstract The Kap Edvard Holm Complex is an early Tertiary layered gabbro situated on the western side of Kangerdlugssuaq fjord. Layered olivine gabbros in Taco Point area are cut by several wehrlitic sill-like bodies which comprise a late ultramafic suite. An intrusive facies inner part consists (+minor chrome-spinel) orthocumulate with clinopyroxene oikocrysts and interstitial plagioclase, kaersutite phlogopite. A replacive occurs marginal zones texturally similar to but contains no...

Palaeomagnetic results are presented from the c. 160 km2 Caledonian synorogenic layered Fongen-Hyllingen gabbro complex (of probable late Silurian age) located about 75 km SE of Trondheim, Norway, in allochthonous Seve-Køli Nappe Complex. A total 80 oriented samples eight sites northern part were investigated. After detailed af demagnetization two stable high coercivity components emerge: one with a well defined NW direction D=325°, I=−21° (α95=8°, N=8), and another, less defined, probably...

Two prominent and similar pumice series were described on Thera in 1879— the Upper Lower Pumice Series (UPS LPS). Since then, geologists have treated two separately because they seemingly occurred at distinct levels had different ages. Here we show that these are identical; there is no LPS Santorini. All stratigraphic conclusions based from Santorini should therefore be discarded. The water-filled caldera with its steep inner slopes existed before eruption. Volcano-tectonic effects...

Abstract Syenitic differentiates from the Fongen-Hyllingen intrusion, which grade downwards into layered gabbroic rocks, give a Rb-Sr whole-rock isochron age of 405 ± 9 Ma and an initial 87Sr/86Sr ratio 0.7047 0.0002. The is interpreted as dating time magmatic crystallisation these final differentiates. Emplacement at 500–600 MPa, followed by amphibolite facies metamorphism, occurred during Middle-Upper Silurian (Scandinavian) orogenic event supports date around 400 for Silurian-Devonian boundary.

The Hyllingen Series comprises the southern part of Caledonian synorogenic Fongen- layered mafic intrusion, which occupies an area 160 km2, southeast Trondheim, Norway. Large, raft-like inclusions form important Scries. Most these are fine-grained, equigranular rocks basaltic composition with lithologies matching those adjacent country rocks. rafts, compose up to 22% lower Series, broadly concordant modal layering in host gabbroic Individual bodies can be 1500 m long and over 100 thick.
