Hey, if its fall in the northern hemisphere then its spring in the southern. Its a win-win. Everyone can be right:-)

A crator is a crator. Lots of them. no reason to say that crator was involved in any exctinct of anything anymore then any other. Lots of impacts would have the same evidence of broken things. the iridium layer is just a layer. Its not evidence for its origin from a impact or killing anything.
its tiny pieces of data made into a impossible claim. Its the k-pg line based on biology that persuades something happened. Yet it was just the flood.
Right. Because global floods tend to leave regional, fine layers of iridium and make impact craters.

Nope. that iridium was just from what followed. it was from volcanic actions that, greatly, is the material above the k-t line. in fact yEC would predict a iridium line from a model where the k-t line was the flood line. The volcanoes exploding all at once some centuries after the flood and the front line of iridium being sorted/deposited first. then the rest on top.
no need for space rocks.
So in the YEC model, the KT boundary marks the end of the flood, and the iridium is from volcanos erupting centuries after the flood? So how did all the strata above the KT boundary get deposited, if it wasn’t by the flood?
That aside, how do you explain the tektites and shocked quartz? Or the giant crater?
Crators are common everywhere.All crators, thousands, would create shocked/surprised minerals.
Yes you have a point about the strata above.
I conclude from my study most of it is, more rare, volcanic material or special cases of sediment from some great surge of the earth.
i mean a creationist must explain the rise of the waters of the ocean to drown the land to bring the present outline. so a earth movement, up/down, must of happened that set off great volcanoes in the americas which caused the volcanic layers, fossilizing creatures too, and here/there pushing sediment loads about.
Above the k-t line there is much less sediment layers then below.
It works.
Iridium is very rare on Earth’s surface but is common in asteroids. The levels of iridium are 30 times greater than average in the Cretaceous/Tertiary (KT) boundary, the layer of sedimentary rock laid down at the time of the dinosaur extinction. A flood couldn’t do this.

how does anyone know iridium scores in space rocks/ it could only be a few and when they hit SMASH. Its speculation. Iridium is not rare in volcanoes if they blow up enough and lots of them all at once.
They don’t know a layer of sedimentary rock was laid at the so called dinosaur extinction event. they just don’t find dinos above some layer. they find other creatures and then this iridium level inbetween in some places. its not flood. its in fact material that was sorted before the sediment following it. the iridium level was laid many centuries after the flood along with the overlying sediment/rock layers.
No need for space rocks. just simple earth processes.
Iridium levels have been measured in meteorites and in surface rocks.

Well they must have some but are the found meteorites good sampling.
Waves don’t produce tektites:
Those are produced by a meteor striking rock, melting it, throwing it up into the air where it resolidifies, and then depositing it in an area hundreds of miles around the impact crater. The K/T tektites all date to the same time period, as we would expect. Floods don’t do this.

And how about the sinkholes in the limestone (that was supposed to have formed during the flood) that just happen to be in a circular pattern around the impact area? How does one explain that when it fits perfectly an impact by a mammoth object from space?
Thats fine. Yes space rocks fell. your invoking a dating concept as opposed to actual geological or geomorphological data.
Volcanoes also produce tektites. But not shocked quartz.

The dating concept is geologic data. It is based on the isotope content of the rocks.

They are defined as non-volcanic here

Admittedly this is something I should be more familiar with since the grad program I’m applying to studies tephra

From that link (emphasis mine):
Often included within tektites are tiny particles of lechatelierite, a very rare, fused silica glass, formed by the melting of quartz crystals by extremely high temperatures and pressures. When associated with tektites, this material is normally used as evidence for shock metamorphism, caused by a meteorite impact event. The presence of these particles is important because obsidian and other volcanic glasses do not contain these particles.

Interesting. One of the major criticisms of the original K/T impact hypothesis was that both iridium and tektites can be volcanic in origin, but the shocked quartz was considered unanswerable.
