How should we deal with geochemical anomalies in stream sediment?
We know that geochemical anomalies in stream sediment usually distributed along the drainage. Therefore, when we use stream sediment as the sampling medium and found an anomaly, we should trace the an …

Can I regard the grayscale of a RGB color image as a panchromatic image?
Here I have a remote sensing dataset with many bands (e.g., blue, green, red, ...), and I use the blue, green and red bands to get a true color image. I want to know if I can get a panchromatic band b …

Can I regard the grayscale of a RGB color image as a panchromatic image?
The workflow of fusing RGB true color image and panchromatic grayscale image can help understand this question. After converting RGB color space to the IHS space, the intensity component is replaced w …

How can we distinguish fold and cycle of sedimentation on a remote sensing image or in the f...
A fold is composed of stratigraphy that is symmetric and repeated. Cyclic sediments (also called rhythmic sediments) are sequences of sedimentary rocks that are characterised by repetitive patterns of …

Can geochemical anomalies of stream sediment samples be used directly for mapping targets?
We know that geochemical dispersion in stream sediment is much widespread, facilitating discovering mineral targets in a regional scale. However, we also know that there should be discrepancy in space …

Why were Fe-oxides not usually used for finding skarn Fe ore deposits in geochemical explora...
I found that Fe-oxides were usually not used for vectoring Fe mineral deposits of skarn type in geochemical exploration. As an indicator element, the common practice told us Fe-oxides should be the mo …
