I am trying to get pressure and temperature of some metamorphic Ca-hornblende and plagioclase assemblages. For temperature, I used thermometer by Holland and Blundy (1994) and obtained good results. For pressure, I used barometer by Anderson and Smith (1995). Most of the resulting pressures are coming with negative values. This is why I want to use the barometer of Bhadra and Bhattacharya (2007).
Dear Mr Gosh.
I found the excel spreadsheet that you are looking for as supplementary data of this article:
Evolution of the Eastern Karakoram Metamorphic Complex (https://doi.org/10.1016/j.tecto.2014.03.023)
I attached the excel spreadsheet that the authors used on their article

Dear Mr. Ghosh
I recommend you to use Gerya et al method:
Gerya T.V., Perchuk L.L., Triboulet C., Audren C. & Sez´ko A.I. 1997. Petrology of the Tumanshet Zonal Metamorphic Complex, Eastern Sayan. Petrology, 5/6, 503-533.
It gives more acceptable results in same cases. Zenk and Schulz (2004) recalibrate it and has Excel spreadsheet:
Zenk, M., and Schulz, B. (2004) Zoned Ca-amphiboles and related P–T evolution in metabasites from the classical Barrovian metamorphic zones in Scotland. Mineralogical Magazine 68: 769–786.
Dear Ghosh
Since spread sheet is not distributed for public, I do not have permission to upload it. But Dr. Schulz will sent you if you ask him via email.
Сережа, у меня есть, то что тебе надо. Обычно я использую в безгранатовых парагенезисах метабазитов калибровки и модели смешения для Amp-Pl геотермометра (Blundy and Holland, 1990) и Amp-Pl-Qz геобарометра (Bhadra and Bhattacharya, 2007). Величины Р-Т параметров метаморфизма пород там рассчитываются при совместном использовании вышеуказанных термобарометров. Если актуально могу выслать эксель файл.
