#Ternary diagram detritus series

In the case of my little space rock, the dot on the graph tells us that it’s primarily a magnesium heavy pyroxene, at around 90% ( 78%). In the A-CN-K ternary diagram, most of the samples close to the plagioclase-K-feldspar join line and to the UCC plot, and in the field of various lithologies of Higher Himalayan Crystalline Series, suggesting that rocks in these series are likely source rocks. These values are also known as enstatite, wollastinite and ferrosilite, respectively. The first diagram displays the proportion of magnesium to calcium to iron in a pyroxene crystal. The geochemical characteristics of shale, including the ratio of elements, discriminant function and ternary diagram location in the study area suggest a passive continental margin sedimentary environment, wherein the terrigenous detritus is mainly derived from felsic igneous rocks in the upper crust, showing characteristics of near-source. There is a correspondence between points of the two ternary diagrams, that is, framework reefs are dominated by generation processes, biodetrital reefs by degradation, and hydromechanical reefs by transportation. orogen was then supplying influential amounts of detritus to these sandstones. Figure 2-Ternary diagram of three major reef classes based on architecture developed by processes shown in Fig. A ternary diagram allows you to display the quantity of each element and determine which kind of species of mineral you’re working with. (a) Ternary plot of the relative abundance of minerals ascribed to the. Each mineral has a basic structure, such as Si2O6 for pyroxene, but they also incorporate a certain amount of magnesium, calcium and iron into their crystal structure. After processing EMP data for the course lab, I did the same for my space rock data and created these spiffy ternary diagrams with Mystat.Ī ternary diagram basically shows the proportion of elements in a certain mineral. However, all that changed with my mineralogy course. It was a fun project, but it left me with a huge Excel spreadsheet of atomic weights, oxide weights and a host of other numbers and abbreviations that I didn’t understand. Oh well.Īs I noted in the last post, I got to do a meteorite analysis with an electron microprobe last summer. kaolinite) however, petrographic results show a predominance of illite (KAl-rich. This may result from either the presence of more clay material or a higher contribution of Al-rich clay minerals (e.g. 5) suggests the studied mudstones have an overall finer grain size than average shale.

But I definitely could have been doing something school related. I dont plot igneous geochemistry diagrams myself - when I collaborated with a petrologist in Vermont, his students all used Deltagraph, because it was the only plotting software that did ternary plots well at all. The SiO 2, Al 2 O 3, and CaCO 3 ternary diagram (Fig. Was it a complete waste of time? Not really. With finals coming up in the next few days, I really shouldn’t have put so much time into processing my meteorite data and making the ternary diagrams.

#Ternary diagram detritus update

New ternary diagrams were generated to reflect the update along with the new values.*

My values for enstatite, wollostanite and ferrosilite were calculated incorrectly.
