ABCD's of MELANOMA
ABCD's of Melanoma.
Malignant Melanoma is the most aggressive of malignant cutaneous tumours. Cases with lymphonode involvement, and distant metastases, carry a very poor prognosis, (50% and 20% respectively alive in 5 years), while those presenting without evident lymphonode involvement have a much better survival rate (60% alive in 5 years).
It is therefore extremely important to do early malignant melanoma diagnosis. There are several criteria that may lead to the diagnosis of a malignant m
Field Journal: Compare

Field Journal: Rocks
This online activity is part of the museum's Online Field Journal Web site, where young children can explore the wonders of nature with the help of an adult. The challenge here is to take a closer look at three rocks: Gowganda Tillite, Loraine Quartzite, and Gowganda Glacial Conglomerate. On the opening page, there are side-by-side photos of the three rocks; students are asked to describe each rock. Clicking a rock's photo takes students to a magnified view of the rock that also asks students tw

Intersecting Isograds at Whetstone Lake
This 15-slide PowerPoint presentation takes the viewer through a real life investigation of metamorphic terrane consisting of pelitic and calcareous rocks. The investigation includes recognition of 5 reactions that take place in the area. P-T, AFM, and T-X diagrams provide visual tools used to assess the conditions under which the metamorphic rocks formed. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Igneous Structures and Field Relationships
This PowerPoint presentation is part of the Whitman College petrology course. The presentation illustrates the structural and field relationships of igneous rocks and igneous processes in pictures, cross-sections, and plan view diagrams. Topics include pyroclastic flows, explosive volcanism, flow area, columnar jointing in basalt, feeder dikes and vents, and numerous other concepts pertaining to igneous rocks. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/N
Igneous Rocks of the Convergent Margins
This set of lecture notes discusses the occurrence and tectonic settings of igneous rocks near convergent plate margins. A discussion of petrography includes major element composition, calc-alkaline trends in ternary diagrams, trace element variations, isotopes to distinguish magma sources, and the origin of igneous rocks at convergent margins. The lecture notes include helpful illustrations, maps and phase diagrams. This resource is part of the Teaching Petrology collection. http://serc.carleto
Igneous Petrology
This PowerPoint presentation is part of the Whitman College petrology course. The presentation provides an introduction to the structure of the earth in the context of the generation of igneous rocks. Slides in the presentation cover the composition of layers of the earth, P-wave and S-wave velocities through layers of the earth, pressure and heat characteristics of the earth, and regions of igneous generation within the earth. This resource is part of the Teaching Petrology collection. http://s
Granitoid Rocks
This 16-slide PowerPoint presentation discusses the characteristics of granitoid rocks including geographic occurrence, rare earth elements, enclave characteristics, pressure-temperature conditions, the influence of water, and tectonic setting.

Geology Collection: Rocks and Minerals Homepage
This site features rock and mineral photographs that can be used for teaching or research. There are pictures of minerals, fossils, and sedimentary, metamorphic, and igneous rocks. There are also images of thin sections of igneous and metamorphic rocks. Sets of images are presented as collections for geology courses. The site also provides information on igneous and metamorphic petrology topics such as metacarbonates, contact metamorphism, regional metamorphism, and blueschists, granulites, and
Geochemistry of Igneous Rocks
This website contains an abundance of data on the geochemistry of igneous rocks. The site provides very brief descriptions of many types of terrestrial and lunar igneous rocks, their regional distribution and classification, and examples of their geochemical trends and fingerprints. Graphs that plot the geochemical composition of both terrestrial and extraterrestrial igneous rocks are also featured. This site could be useful for upper level geology students doing independent research, as well as
General Classification of Igneous Rocks
These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The general chemical classification covers silica content (silica saturation), aluminum saturation, and alkaline and subalkaline rocks. This resource is part of the Teaching Petrology collection. http://
