The image above represents actual mass of geological body.

To compute for actual mass of geological body three essential parameters are needed and these parameters are **Total Anomalous Mass (M _{E}), Anomalous Density of the Body (ρ_{1}) **and

**Host Rock Density (ρ**

_{0}).The formula for calculating actual mass of geological body:

M = M_{E} (^{ρ1} / _{ρ1 – ρ0})

Where:

M = Actual Mass of Geological Body

M_{E} = Total Anomalous Mass

ρ_{1} = Anomalous Density of the Body

ρ_{0} = Host Rock Density

Let’s solve an example;

Find the actual mass of geological body when the total anomalous mass is 12, anomalous density of the body is 21 and the host rock density is 13.

This implies that;

M_{E} = Total Anomalous Mass = 12

ρ_{1} = Anomalous Density of the Body = 21

ρ_{0} = Host Rock Density = 13

M = M_{E} (^{ρ1} / _{ρ1 – ρ0})

M = 12 (^{21} / _{21 – 13})

M = 12 (^{21} / _{8})

M = 12 (2.625)

M = 31.5

Therefore, the **actual mass of geological body **is **31.5 kg.**

**Calculating the Total Anomalous Mass when the Actual Mass of Geological Body, the Anomalous Density of the Body and the Host rock Density is Given.**

M_{E} = ^{M} / _{(ρ1 / ρ1 – ρ0)}

Where;

M_{E} = Total Anomalous Mass

M = Actual Mass of Geological Body

ρ_{1} = Anomalous Density of the Body

ρ_{0} = Host Rock Density

Let’s solve an example;

Find the total anomalous mass when the actual mass of geological body is 45, the anomalous density of the body is 12 and the host rock density is 10.

This implies that;

M = Actual Mass of Geological Body = 45

ρ_{1} = Anomalous Density of the Body = 12

ρ_{0} = Host Rock Density = 10

M_{E} = ^{M} / _{(ρ1 / ρ1 – ρ0)}

M_{E} = ^{45} / _{(12 / 12 – 10)}

M_{E} = ^{45} / _{(12 / 2)}

M_{E} = ^{45} / _{6}

M_{E} = 7.5

Therefore, the **actual mass of geological body **is **7.5 kg.**
