Harker diagrams explained
WebAll elements data were plotted to various diagrams to classify rocks, determine magma affinity, and construct petrogenetic models for the research area. 4. Results 4.1. Mineralogy of Rocks from Ungaran and Muria Volcano Mineralogy of rocks from both volcanoes are significantly different, which is further explained by geochemistry. WebQuestion: from a Harker diagram when a mineral begins to crystallize Manganese does not form its own mineral in lavas, but instead it substitutes into other minerals. In the case df Thingmuli lavas, whic element(s) show trends similar to Mn 6. h mineral(s) are the most likely for Mn substitution? To determine this, note which other Bonus Question.
