Looks like galvanic corrosion. If you look closely it appears to be around the steel pan bolts and aluminum crankcase threads.
Galvanic corrosion is typically caused when two dissimilar metals are improperly coupled together in a corrosive environment.
Galvanic corrosion is caused by an electrochemical reaction between different classifications of metals rubbing against each other in wet or grimy conditions. This type of corrosion commonly occurs between aluminum and cast iron; copper and steel; and stainless steel and aluminum.
