Hi Eduardo,

Are you intended to estimate the original magmatic crystallization temperature or the late metamorphic event T?

Hi Eduardo,

The attached papers may be of some use regarding the formation of the titanite rims on the ilmenite as function of P-T-XCa.

Dear colleagues, 

I have been working with migmatites that has a metasyenogranite as a preserved protolith. This rock is composed of igneous quartz, k-feldspar plagioclase, biotite and ilmenite crystals. Due to metamorphism, it has formed garnet, a new generation of k-feldspar and titanite (I have attached some photos to illustrate it and, hopefully, I will have an article about it soon). However, work with the thermobarometry of this rock has shown challenging, since THERMOCALC and DOMINO bugs when I use its composition and the Ti-in-Quartz calibration haven't presented realistic results.

Any articles and suggestions to solve this issue are appreciated.

Thanks in advance!

Regards,
