Subject: Differential impedance

I have a question regarding differential signal pairs and differential impedance that I hope someone can help me with. We are designing a 14 layer board and the finished thickness needs to .062" and we require 100 ohms. Some of the internal layers we have split planes. Would these be considered strip line or microstrips?

Thanks

Scott
