A Novel Approach to Edge Detection for a Gravity Anomaly Based on Fractal Surface Variance Statistics of Fractal Geometry

Round 1

Reviewer 1 Report

 

 

I recommend publication of this article with some minor changes.

 

1.       In Figure 4, extend the scale up in the right side of each map 4a to 4f. Also, and skip one or two of the Fractal dimension values for example………… in Figure 4a, from bottom to top write 1.9, skip 2.01 and 2.03 then write 2.05 …………and so on……….. use bold font and enlarge font size a little.

2.       Figure 5., the same like the previous comment.

3.       In Figure 6, use 6a, 6b, 6c, 6d. You missed the scale for in two figures.

4.       In Figure 7., use different N arrow, and you forgot the scale bar in the three maps.

5.       In Figure 8., N arrow and horizontal scale are missing. Also, for the color scale  extend it up and the same like comment # 1.

6.       In Line 290, correct discussion and conclusion to “conclusion” only and use separate section for the conclusion.

 

7.       IN section 3., Geological conditions of the study area, change it to result and discussion., then use this “Geological conditions of the study area” as a subtitle from the result and discussion.

Reviewer 2 Report

The paper has revisited the fractal geometry principles to identify the presence and edge detection of geological anomalies, rather the presence of faulted zones by using Magnetic and gravity analysis.

However, a discussion on comparative analysis between gravity and magnetic anomaly based edge detection of the anomalies would have enhanced the quality and interest. Further how will the gravity analysis work along the EW (horizontal plane)? This may be important for flat, tabular or horizontal ore bodies, although such ore bodies are rare, the method should be inclusive. 

Similarly, the detection of magnetic anomalies in the Horizontal plane along EW or vice-versa need some proper justification in the light of skewness of magnetic fields along the horizontal plane.

Also, when the paper states geological anomalies then a host of anomalies come into picture, namely, fault, fold, joints intrusions, other discontinuities etc. How could such discontinuities be identified alongwith their edges?

Nevertheless, the paper adds a new dimension to the edge detection and could provide reasonable insights.
