Amphibole Thermobarometry and Chemometry

You need to install Thermobar once on your machine, if you haven’t done this yet, uncomment the line below (remove the #)

[1]:
#!pip install Thermobar

Load python things

[2]:
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import Thermobar as pt
pd.options.display.max_columns = None

Load data

[3]:
out=pt.import_excel('Amphibole_Liquids.xlsx', sheet_name="Amp-Liq")
my_input=out['my_input']
Amps=out['Amps']
Liqs=out['Liqs']

Checking data read in correctly (check no columns are full of zeros that you think you inputted)

Example 1 - Amphibole-only pressure

  • can use help functions to see equation options

[5]:
help(pt.calculate_amp_only_press)
Help on function calculate_amp_only_press in module Thermobar.amphibole:

calculate_amp_only_press(amp_comps=None, equationP=None, T=None, deltaNNO=None, classification=False, Ridolfi_Filter=True)
    Amphibole-only barometry, returns pressure in kbar.

    Parameters

Ridolfi 2021 - Minerals algorithm

  • here, we specify equationP=“P_Ridolfi2021”, which combines equations 1a-1e from Ridolfi 2012 and chooses the “correct” equation using a number of filters (see Ridolfi 2021, Minerals)

  • The output dataframe shows the calulated pressure, as well as the equation selected

  • The code also prints a warning that some of the rows have oxide sums <90, so a Nan is returned for these following Ridolfi 2021 supplement

  • If you want to use the pressures which yield “input errors”, you can specify “Ridolfi_Filter=False”

  • This is more for looking at what ones it has discarded, we don’t necessarily recomend this, we just have it as a feature you can use at your peril.

Example 2 - Amphibole-only temperatures

  • Unlike pressures, some thermometers are sensitive to P

  • here, we calculate tempeatures for P=5 kbar

Example 3 - Iterating P and T

  • We can also iterate pressure and temperature - most barometers are actually T-insensitive, so it isn’t actually iterating, but instead calculates the pressure first, then uses this to calculate the temperature (which does depend on P).

Youve selected a P-independent function
Note - Putirka 2016 spreadsheet calculates H2O using a H2O-solubility law of uncertian origin based on the pressure calculated for 7a, and iterates H2O and P. We dont do this, as we dont believe a pure h2o model is necessarily valid as you may be mixed fluid saturated or undersaturated. We recomend instead you choose a reasonable H2O content based on your system.

Example 8 - Calculating melt compositions from amphibole compositions.

  • You need to specify amphibole compositions.

  • For some equations, e.g., equation 3 and 5 from Zhang, Putirka (2016) SiO2 content you also need to specify temperature.

  • If you don’t, it returns a warning telling you that you won’t get results for 3 equations unless you enter a T.
