I've had a quick read of this article and it looks to be at or about GA-level, but I'm first going to work my way through the article in a bit more detail.
Overview -
The first paragraph states: No broad blocks as old as 3 Ga are found in Precambrian shields. Toward the end of the Archean, however, some of these blocks or terranes came together to form larger blocks welded together by greenstone belts.[2]. Ga is not defined
In the same sentence, it is suggested that "blocks" and
terranes are alternatives/comparable/identical (it's not clear what the relationship is, but the terms "crustal block" and named blocks do occur in
terranes). We then have blocks (or terrances) becoming bigger blocks, well yes but presummably they could be bigger terranes (the next paragraph is all about terraces)?
