Also in and around the area were large numbers of burnt animal bones - further evidence for repeated fire use for cooking meat. Shahack-Gross and her colleagues have shown that this organization of various "household" activities into different parts of the cave points to an organization of space - and a thus kind of social order - that is typical of modern humans.
She said that these findings help them to fix an important turning point in the human culture development - that in which humans first began to regularly use fire both for cooking meat and as a focal point - for social gatherings.

230Th/234U dating on speleothems in the cave identifies that they were occupied from before 382,000 BP possible as early as oxygen isotope stage 11 (420 to 360 kya). The cave occupation ended before 152,000 years ago, possibly shortly after 207,000 years ago.[3]

The dated speleothems would coincide with the strata in which the artifacts (and fire remnants) were found. They formed at the same time the strata were laid down and can therefore be used to date the artifacts.

First, speleothem is sort of a generic term for things like stalagmites that form in caves. It can be determined when they formed by the amounts of slightly radioactive materials within them.
Now, over time stuff (dust, dirt, crud) builds up on the floor of the cave, getting deeper and deeper. If a speleothem which is 300,000 years old is covered up by crud it must mean that the crud (and everything in that same layer of crud) is less than 300,000 years old. But if stone tools and bits of charcoal are found in the same layer of crud as that speleothem, it must mean that those tools and charcoal were left there at the same time that the speleothem formed. If they are deeper, then they are older.
Does that help?
And thanks for the compliment.
