The image above represents bourger anomaly. To calculate bourger anomaly, three essential parameters are needed and these parameters are **Free Air Correction (g _{F}), **

**Bouguer Correction (Î´g**and

_{B})**Terrain Correction (Î´g**

_{T}).**The formula for calculating bourger anomaly:**

g_{B}Â = g_{F}Â – Î´g_{B}Â + Î´g_{T}

Where:

g_{B}Â = Bouguer Anomaly

g_{F}Â = Free Air Correction

Î´g_{B}Â = Bouguer Correction

And, Î´g_{T}Â = Terrain Correction

Let’s solve an example;

Find the bourger anomaly when the free air correction is 14, the bourger anomaly is 18 and the terrian correction is 20.

This implies that;

g_{F} = Free Air Correction = 14

Î´g_{B} = Bouguer Correction = 18

And, Î´g_{T} = Terrain Correction = 20

g_{B}Â = g_{F}Â – Î´g_{B}Â + Î´g_{T}

That is, g_{B} = 14 – 18 + 20

g_{B} = 14 – 38

g_{B}Â = -24

Therefore, theÂ **bourger anomalyÂ **isÂ **-24 mGal.**

**Calculating the Terrian Correction when the Bourger Anomaly, the Free Air Correction and the Bourger Correction are Given**

Î´g_{T}Â = g_{B} – g_{F} + Î´g_{B}

Where;

Î´g_{T}Â = Terrain Correction

g_{B}Â = Bouguer Anomaly

g_{F}Â = Free Air Correction

Î´g_{B} = Bouguer Correction

Let’s solve an example;

Find the terrian correction when the bourger anomaly is 48, the free air correction is 22 and the bourger correction is 14.

This implies that;

g_{B} = Bouguer Anomaly = 48

g_{F} = Free Air Correction = 22

Î´g_{B} = Bouguer Correction = 14

That is, Î´g_{T}Â = g_{B} – g_{F} + Î´g_{B}

Î´g_{T} = 48 – 22 + 14

That is, Î´g_{T} = 26 + 14

Î´g_{T} = 40

Therefore, theÂ **terrian correctionÂ **isÂ **40.**
