If an asteroid created the moon..... where is the impact crater?

I was just looking at a 6.8 earthquake in India in Google Earth (the solid red star) - when I noticed something.... are the Himalayas the outer rim of the impact site?

Wow - if it's not - I would like to know where else the impact that created the moon could possibly be....

I just read an article that stated that the sun and the earth are not related. ie The sun was formed much earlier than the earth. Perhaps all the parts in our solar system are "captured" items of the sun. Something to think about. Frank

I don't think your site is circular enough, Mark.

Consider the Aleutian Island chain as part of the arc of an impact center, based somewhere near the Kamchatka Peninsula.

Age also needs to be a consideration. Would have to be from the 3.9 billion year (+/-) old bombardment which is believed to have delivered most gold to the Earth as well. Recent work notes most known gold deposits on Earth are not associated with core material and have not been evenly distributed in the Earth's composition. Most appears to be comparitively shallow, indicating a younger arrival time. Earth currently believed to be about 4.55 billion years old.

Interesting how major impacts seem to have delivered many Rare Earth Metals to the Earth. The dinosaur extension event at was identified from relatively increased levels of iridium in the Cretaceous-Tertiary level. All iridium currently on Earth (as well as platinum, palladium, osmium, indium, etc) arrived via asteroid or meteorite impacts.

I've always thought it was the entire Pacific Ocean...did tectonic plates exists before the impact?

I don't know. I presume so. But the plates have been altered by time, meteorite impact sites, and vulcanism. Tectonic plates get recycled too, slowly. And as that happens, most of the iron goes toward the center of the earth, along with some nickel and heavier metals. And as the plates migrate over the crust of the mantel, new lava is erupted onto the surface.
