The image above represents bourger anomaly.

To compute for bourger anomaly, three essential parameters are needed and these parameters are **Free Air Correction (g _{F}), **

**Bouguer Correction (δg**and

_{B})**Terrain Correction (δg**

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

g_{B} = g_{F} – δg_{B} + δg_{T}

Where:

g_{B} = Bouguer Anomaly

g_{F} = Free Air Correction

δg_{B} = Bouguer Correction

δg_{T} = 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

δg_{B} = Bouguer Correction = 18

δg_{T} = Terrain Correction = 20

g_{B} = g_{F} – δg_{B} + δg_{T}

g_{B} = 14 – 18 + 20

g_{B} = 14 – 38

g_{B} = -24

Therefore, the **bourger anomaly **is **-24 mGal.**
