Thank you so much for this video! Clear and comprehensive. Finally found an explanation that helps by building basic understanding of the concept fractional crystallization. Helped me study for my final exams
Thank you so much for the presentation, very well presented 👏. I just would like to ask on the textural evidence part in which in the outcrop that was shown there's a rhythmic pattern of cumulates, just wondering why did the cumulates have settled out in such a pattern forming those interlayered feature? and not just as a whole? (like the entire olivines were fractionated out)
Thank you for the video. I have a question on the concentration of elements. If for example we're in a phase of crystalizing Olivine (Mg,Fe)2[SiO4] and Clinopyroxene Ca(Mg,Fe)[Si2O6], can we say that all other elements (Si, Ti, Al, Na, K, P, Mn) are concentrating in the magma melt? and can we consider all of them incompatible in this case?
Yes, the incompatible elements will concentrate in the melt. All the ones you listed would increase, except maybe silicon. Silicon would increase if the melt has more than the crystallizing phases can hold.
Thanks for the Video Can I please ask, how can one determine magmatic process of gabbro being given geochemical, petrographic and geochronological data ?
You can do very much with that data. Each of those bits of information you described will unravel the crystallization, temperature and pressure history of the gabbros.

Masterpiece presentation. Thank youuu

Perhaps timing of different pules of olivine. Or maybe there are currents in the chamber causing settling pulses.
Thank you for the video.
