TLDR
The late Quaternary phonolitic pumice deposits of Tenerife, Canary Islands, are the product of a periodically-tapped, periodically-replenished, zoned alkaline magma system as mentioned in this paper.About:

The agpaitic rocks : an overview
TL;DR: Agpaitic nepheline syenites are characterized by extremely high contents of rare elements such as Li, Be, Nb, Ta, REE, Zr, Th, etc. as discussed by the authors.

Crystallization and eruption ages of Breccia Museo (Campi Flegrei caldera, Italy) plutonic clasts and their relation to the Campanian ignimbrite
TL;DR: In this article, the ages of plutonic ejecta clasts were determined via uranium decay series and (U-Th)/He dating of zircon, with an average age of 49.7 ± 2.5 ka.

Evidence for Fractional Crystallization of Periodically Refilled Magma Chambers in Tenerife, Canary Islands
Else-Ragnhild Neumann,E. Wulff-Pedersen,S. L. Simonsen,Norman J. Pearson,Joan Martí,J. Mitjavila +5 more
TL;DR: In this article, the trace element data on basanitic to phonolitic lavas of different ages and from different parts of Tenerife (Canary Islands) have been used to obtain more detailed information about processes taking place in crustal magma chambers fication by fractionation processes.

A global review on agpaitic rocks
Michael A.W. Marks,Gregor Markl +1 more
TL;DR: A review on agpaitic rocks can be found in this article, where the authors provide a summary of the fluid inclusion record of miaskitic and ag paitic assemblages as fluids play a key role in the evolution of peralkaline rocks.

The iron-titanium oxides of salic volcanic rocks and their associated ferromagnesian silicates
TL;DR: In this article, the coexisting microphenocrysts of magnetite and ilmenite together with the ferromagnesian silicates in salic volcanic rocks have been analyzed with the electron microprobe.

Volatile oversaturation during the evolution of silicic magma chambers as an eruption trigger
TL;DR: In this paper, it was shown that the uppermost part of the chamber will become oversaturated in water, generating an excess pressure by equating the magma and chamber volumes at some pressure above the stable lithostatic value, this excess magmatic pressure can be evaluated as a function of the magnma's compressibility, water content and solubility, and some assumed measure of chamber's ability to expand.
