[@saitama480]

These are the best and complete videos on crystallisation series on you tube...

[@yashvant254]

Great sir thanks a lot keep blessing on us like this 🙏

[@adnanbarkat2684]

What will be the amount of melt produced at the eutectic for An: Di=50:50?

[@shahrukhmeh]

Thank you sir I’m currently studying in sweden and your videos are really helpful .. love from 🇸🇪 🇵🇰

[@skbcreation236]

Thank you sir ,for clearly explaining eutectic crystallization.🙏

[@santalkola2045]

Thanks you sir...🙏

[@venkatasrikanth245]

Very good explanation,watched so many videos, but this is so comprehensive. Thanks geomind.

[@muralimohan3914]

Thanq you sir Sedimentology classes continue sir plz

[@bikashranjanmahanta9595]

Thanks for your clarification sir❤️❤️

[@StaytunedwithmosME]

Thankyou Sir, your explanation was very helpful for me to understand . I was really facing difficulty to understand the phase diagram and couldn't get any exact video on youtube. But lucky I'm to found your channel .. thankyou sir... Keep on making helpful videos like this

[@Geo_Mind]

Thank you so much Mosmi

[@timeforkpop7305]

What is phase equilibria conditions for this system

[@nimraahsan3450]

Very well explained.👍 Thank you Sir!

[@tariqmasood7501]

fabulous teaching with simple explanation. I am a bit average student so there's a thing I didn't understand. Why diaopside can't react with the melt as soon as crystallisation starts? Why there can't be peritectic point in this system? Thank you.

[@Geo_Mind]

1. because as soon as crystallization starts, there is insignificant amount of diopside which is forming. 2. that depends on the type of components.

[@Rahuwiki468]

Thank you sir

[@abrcblover6689]

Thank You Sir🙏🙏🙏❤❤

[@vedangpatankar9000]

Great video again sir..at 23:04..the 6th line of paragraph 6..says that the system is 43% diopside crystals (An0) and 57% liquid of composition An 25. Shouldnt that be An 20 instead of An 25? if not can you explain how An 25 came in between

[@Geo_Mind]

Yes Should be An20, just a typing mistake.

[@poulamimidya1235]

Sir can we get a video on exsolution??

[@Geo_Mind]

Its already there on GeoMind app, Igneous Petrology

[@kmbhuvneshrajpoot1943]

Thank u so much sirji

[@adnanbarkat2684]

(d) At the eutectic, melting continues until one of the solid phases is fully molten. For the 50% anorthite 50% diopside mixture, which phase is consumed at the eutectic?

[@Geo_Mind]

Both

[@supriyaagrahari2590]

I m not sure but acc to lever rule For diopside crystals 20÷42 should be there instead 22÷42.🤔

[@Geo_Mind]

the eutectic composition is at An42 , so tie line EF is 42 units, for An20 bulk the crystal % at E will be 42-20= 22/42

[@Geo_Mind]

Count the units , the tie line is 22 for crystal of Di, for concept of lever rule watch previous video.

[@supriyaagrahari2590]

Sir i got 42-20 But somewhere i studied opposit side to the crystal is considered. Ex - for crystal diopside melt portion should be count and for melt crystal portion should be count.plz explain sir🙂

[@supriyaagrahari2590]

Even i went through its previous video, umentioned solidus side will represent liquid

[@Geo_Mind]

@@supriyaagrahari2590 the portion of tie line which touches the liquidus curve side will represent the Crystal % I have provided a diagram for reference in this video.

[@supriyaagrahari2590]

Sir in ur previous vid u mentioned solidus side represent liquid so for diopside crystals calculation, opposite portion should be take into consideration .Plz explain sir🙄

[@Geo_Mind]

I was talking about the tie line, if the portion of tie line touches the solidus curve then that portion of tie line will represent the liquid % (by counting the units) I can't be more clear than this.

[@supriyaagrahari2590]

Thanq sir I got it🙂🙂

[@balwantsinh531]

Sir ye shayad immiscible liquid ke liye he,, right !!

[@the_travel_turtle]

Thnq sir ❤️

[@ashutoshmishra4013]

Sir...i have a doubt ..how we decide the bulk composition. I mean when An42 Di 58 then crystallization begins left side . So how come An 43 Di 57 change the crystallization pattern..still Di composition is higher? Can you explain this please 🙏🙏

[@Geo_Mind]

Its the composition for those two particular minerals.

[@lemnaiwangnawlemnu7955]

Can I get this pdf

[@pritamff6867]

Sir i have a doubt that on the left side of crystallization after reaching eutectic point, diopside will crystallze about 52 percent and the remaining 48 % is liquidous.. is the 48 % liquid contain both anorthite and dipside or are we talking about diopside only.?

[@shrabaneenaik7255]

If An 42 & Di 58 at E point then An20% & Di80% how it will form?

[@studywithadarsh2019]

Please upload metamorphic texture or structure

Please tell me: Texture on liquids line Texture at eutectic point

[@palak9985]

Sir, Is it correct that the discontinuous series show the fractional crystallization while the continuous show equilibrium??.....and sir one more question that, Does the plutonic and volcanic equivalent formed by equilibrium crystallization (with same bulk composition)??

[@Geo_Mind]

No, In real world scenarios Fractional melting is more dominant.

[@studywithadarsh2019]

Please...make on video .of numerical

[@ashim1656]

Sir please provide a note

[@jahnuhaza5728]

Add metamorphic in equilibrium, mineralogical phase rule etc

Sir I am ...doing Bsc . in Geology and wants ....to know whether IIT have geology as a subject .If it is there then which exam we have to sit to qualify.....!

[@Geo_Mind]

Yes several IIT have geology and other related subjet, You can appear for IIT JAM after BSc and GATE after MSc

[@vdoraiburu1696]

@@Geo_Mind Thank you very much SIR ...for clearing my doubt.🙏

[@amarkandasamy2008]

kindly explain in english ... amar from tamilnadu

[@jidduguramu8805]

Explain in English sir

[@nandiphabuhledhakana5675]

How I wish everything was explained in English😥 however I am learning one thing or two despite the language barrier. These videos are helping earth science students across the globe
